Los 10 - Moritz Grossmann - Chronoscop - A historically important Glashuette chronograph, so called CHRONOSCOP. According to our research, this watch is the only Grossmann Chronoscop and second time offered at auction! Case No. 3813, Dimensions 52 mm, circa 1880, Weight 112 g, Origin Deutschland Case: Silver, guilloche pattern. Dial: Enamel. Movm.: 3/4 plate movement, large gold screw compensation balance. Carl Moritz Grossmann was born in Dresden on March 27, 1826; his father was a sorter at the Royal Court Post Office. Moritz grew up in modest circumstances, but his teachers at school soon realised that he was an exceptionally gifted pupil and he received a free place at the "Technische Bildungsanstalt" (which was later to become Dresden’s Technical University). This enabled him to study for two years – just like Ferdinand Adolph Lange some years before him. In 1842 Grossmann began his apprenticeship with the watchmaker Gottfried Friedrich Kumme (sen.) in Dresden and was allowed to end his apprenticeship early because of his unusual talent. He also learnt English, French and Italian; at the same time Grossmann became friends with the watchmaker Ferdinand Adolph Lange, who was 11 years older. Both men were ambitious and meticulous workers, keen to learn and to build watches. His travels took Moritz Grossmann to Altona in 1847 where he worked with chronometer maker Moritz Krille; afterwards he went to stay with watchmaker to the Munich court Josef Bierganz. He went on to La Chaux-de-Fonds, the Swiss stronghold of the watchmaking industry; from there he traveled to England, France, Denmark and Sweden, always on the lookout for opportunities to learn and further his knowledge and abilities in watchmaking. He only returned to Dresden for a short while in 1854 before moving to Glashuette, about 30 km from Dresden. In Glashuette Grossmann invented the "Glashuetter Drehstuhl", a small watchmaker’s lathe. He began devoting himself to the construction of lever escapements and tried to perfect the pivoted detent escapement. He also built precision tools, movement models, fine pocket watches and marine chronometers. Grossmann mastered this multitude of tasks with a team of highly qualified colleagues; he was able to win the two expert watchmakers Ludwig Strasser and Carl Maucksch for his workshop. This allowed Grossmann not only to build his own watches but also pass his knowledge on to others. Grossmann gave lectures, wrote articles for national and international horological magazines and translated technical books such as Claudius Saunier‘s textbook on watchmaking "Lehrbuch der Uhrmacherei", which consisted of several volumes. In 1866 Grossmann was the first German to win a competition at the British Horological Institute in London with his paper "On the detached lever". Moritz Grossmann was also very socially and politically active; he founded the volutary fire brigade of the sports club in Glashuette, the military club and supported the building of the railway link to the Mueglitz valley. After his wife died in 1871, he remarried and the couple had three children. In 1876 Grossmann became a member of the state parliament of Saxony. He initiated and created the concept for the German Watchmaking School in Glashuette; he founded the school in 1878 and served as its first chairman of the board and taught maths and languages at the school. Moritz Grossman died after a stroke on January 23, 1885 in Leipzig, shortly after holding a lecture on the introduction of Universal Time. Just like his friend Ferdinand Adolph Lange he was only 60 years old when he died. After Grossmann’s sudden death his factory in Glashuette was dissolved. Sincere thanks are given to the Grossmann Uhren GmbH for the text and the information provided. Case: very good. Dial: very good. Movm.: very good, cleaning needed.

Dial: Silvered. Movm.: Rectangular-shaped brass movement, Graham escapement with adjustable steel pallets with inlaid sapphires, nickel steel compensation pendulum type 11, pendulum spring suspension. In 1875 Ludwig Strasser and Gustav Rohde founded the company "Strasser & Rohde" in Glashuette. It produced all differents kinds of precision pendulum clocks, among them clocks with inverted escapements. The product range also included marine chronometers, escapement models, precision tools, tachometers, time ball clocks, timer clocks for safes, pocket watches, coincidence clocks, stopwatches and other timers. In 1879 Strasser began to devote most of his time to the German watch and clockmaking school in Glashuette and eventually left the company. When Rohde retired, Wilhelm Kreis took over the company. Paul Weiss leased the company from Kreis in 1918 and later took it over when Kreis died. While Kreis had still sold about 300 Strasser & Rohde precision pendulum clocks, only a handful of them were sold during the time of Paul Weiß. The last pendulum clock by Strasser & Rohde was delivered to the observatory in Greece on June 19, 1959. It was a large type B I clock with 24 hour dial, lateral weight guiding system, electrical contacts and a Riefler J-pendulum. Case: very good. Dial: very good.

Los 28 - Willy Triebold - Echt Glashütte - An important, very fine and extremely rare Glashuette pocket chronometer with spring detent escapement, made by one of the most talented students at the Glashuette watchmaking school Movm. No. 1656, Cal. 50, Dimensions 67 mm, circa 1904, Weight 236 g, Origin Deutschland, Original box Case: Silver, gold crown and hinge, glazed movement. Dial: Enamel. Movm.: 3/4 plate movement, screwed gold chatons, spring detent escapement, large gold screw compensation balance, freesprung blued helical balance spring, very finely engraved balance cock, gold escape wheel. Wilhelm Triebold was born 1880 in Hessisch-Oldendorf, south west of Hannover. In 1894 he began his career by starting an apprenticeship; in 1898 he moved to Berlin as a journeyman. He worked as assistant to watchmaker Franz Ludwig Löbner (1836-1921). During his stay in Berlin he invented many watchmaking tools and pocket watch components, which he consecutively published in the Deutschen Uhrmacherzeitung (German watchmaker’s magazine) in 1899. Among his inventions were a holder for screws and a novel system for attaching bow and pendant to the case. Triebold held over 30 horological patents. His talent was quickly recognised and the German association of watchmakers recommended him to the Royal Prussian ministry of Trade and Commerce. The ministry granted Triebold a scholarship at the German watchmaking school in Glashuette,where he trained from May 1904 to June 1905. During this time he proved himself as outstanding watchmaker by creating four timepieces: - (school watch) no. 1593 chronometer model with escapement - no. 1610 – a pocket watch with lever escapement - no. 1657 – a chronometer tourbillon - this pocket chronometer no. 1656. The chronometer tourbillon with his own calibre design dating from 1905 he created as special school no. 1657. The 50 mm movement featured a chain/fusee drive with a crown winding mechanism. This tourbillon was the third tourbillon created by a student at the school. It is the last one of three such pieces created under the direction of Gustav Hesse who taught at the school from 1881 and 1915. This watch was sold at Sotheby’s in Geneva on May 19, 1998 for 166.300 CHF (incl. fees). An article in the German watchmaking magazine dating from May 15, 1905 states that in this year Triebold was the only recipient of the prize awarded by the school for outstanding theoretical knowledge and practical skills. He also received an honorary diploma awarded by the Grossmann foundation for his remarkable talent. In the same year, Triebold oresented his three timepieces at the historical watch exhibition in Nuremberg and was awarded a silver medal. In 1911 Triebold opened a shop in Hannover, where he sold watches from Geneva and Glashuette, he also sold Gruen-Alpina watches. Triebold was a member of Saxonia, where his nickname was "Matador". The Saxonia fraternity was founded in 1895 by students at the German watchmaking school to spend their evenings talking shop, to promote community spirit and forge links fort he future. In 1904 the "Altherrenbund der Saxonen (A.H.)" was established. Upon finishing their training the students automatically became members of the A.H. When a former student returned to the school for further studies such as a master’s certificate, they were reassigned to the A.H. Triebold was also a passionate collector of watches and one of the most prolific collectors of his time. He was close to Carl Marfels, who was the most important collector of the early 20th century. Unfortunately Triebold‘s collection was almost completely destroyed during WW2. In the night of October 8th 1943 Hanover suffered the worst bombardment of WW2. 261.000 bombs fell on Hanover leaving 1,245 people dead and the city a field of debris. The city centre, grown over centuries was almost completely destroyed. The Aegidius church burned out and the houses in Georgstrasse collapsed. Only the Kroepke clock remained standing. n Klassik Uhren 4/2006 Jürgen Abeler wrote: "Many of his Renaissance watches were kept in a heavy iron strongbox. During a heavy bombing on Hanover the Triebold house burned down completely. When the strongbox was eventually opened, the wooden shelves were charred and a tar-like matter covered all brass and steel watch parts, which could not be removed with normal cleaning materials. In our workshop we carried out tests with rare acids as well as as formic and bromic acid an eventually found a way to clean the watches". The Triebold company continued their business in Hanover after the war. The remaining collection was split up after Triebold’s death and is scattered to the four winds today. The historical Museum in Hanover owns a well-preserved tower watchman clock from the Willy Triebold collection. Triebold had stated that he acquired the watch in parts from a second-hand dealer at Burgstrasse in Hanover in 1920/1930 and declared that the parts came from the rubble that was cleared from the attic o

Los 34 - A. Lange & Söhne - SAXONIA - A remarkable, carefully looked after Glashuette wristwatch with Lange oversize date. This is the first reference model 102.002! After its presentation in 1994, the watch was delivered to Jewellers W. Becker & Cie. KG in Hamburg. The watch comes with the original black leather case with outer box (originally light grey), certificate of guarantee, user instructions and delivery note, confirming delivery to Jewellers W. Becker & Cie. KG, dated 29.03.1995 and described as "Nr. 1 von Modell 102.002" (No 1 of model 102 002) Ref. 102.002, Cal.

Dial: Solid silver, argenté, blued steel hands. Movm.: Manual. This watch is the first SAXONIA reference 102.002, which was ever delivered to a jeweller. It is in excellent condition and constitutes a milestone in the history of the company A. Lange & Söhne. After the company A. Lange & Söhne was established by Walter Lange and Günter Blümlein in 1990, the manufactory presented their first four watch models at Dresden Castle to an excited audience in 1994. Together with the Arkade, Lange 1 and the Tourbillon Pour le Mérite, came the 33,9 mm Saxonia with Lange oversize date, as reference 102.001 with gold hands and 102.002 with blued steel hands. The timepieces were delivered to selected jewellers in the following spring. The early SAXONIA has a distinctive 33,9 mm case and is 9,1 mm high. From a lateral view the three-part case is reminiscent of a layer cake. Small diamond-shaped hour markers surround the dial. The Lange oversize date, which lends the watch its distinctive appearance (even if the window appears a little large for the case size), was inspired by the Semperoper in Dresden and registered as a patent in 1992. The first SAXONIA models reference 102.001 and 102.002, were powered by calibre L911.3, which was also used in the Arkade model, which was inspired by the design of the arcade at the Dresden Zwinger. Case: very good. Dial: very good. Movm.: very good, capable of running, cleaning recommended.

Los 39 - A. Lange & Söhne - LANGE 1 Blue Series - A very attractive and rare white gold Glashuette wristwatch with Lange oversize date, power reserve indicator, twin barrel, 72 hours power reserve and deep blue dial. This watch was given a general overhaul at A. Lange & Söhne in May 2023 and has not been worn since Movm. No. 27644, Ref. 101.027, Cal.

Dial: Solid silver, deep blue. Movm.: Manual. The unusual subsidiary time and second indications and the off-centre large date window make the LANGE 1 a model with an extremely high recognition value. It was one of the first models the brand launched after their re-formation in 1994 and it quickly captured the hearts and souls of the public. Today it is one of icons of the brand. This reference 101.027 was launched in 1997 and is quite different from other LANGE 1 models. This is the first LANGE 1 in white gold, as well as the first blue dial produced by Lange. A. Lange & Söhne created an exclusive deep dark blue dial which lends the watch a particular flamboyant look to stand out among its peers. Even though the series was not limited only few pieces of the "blue edition" were produced, which makes it a rare and highly coveted variant. The design was so popular that in 2017 A. Lange & Söhne launched the second generation of the blue dial models as reference 191.028. This early example of the LANGE 1 "blue series" is powered by manual-wind calibre L 901.0, which features an exquisitely finished ¾ nickel silver plate and comes with a power reserve of up to 72 hours.

Dial: Black. Movm.: Manual. The LANGE 1 reference 101.035 produced in small quantities exclusively between 1999-2006 sets itself apart from its breed. Dressed in platinum with a distinctive monochromatic all black configuration and a handsome white on black date disc, the model was nicknamed by collectors "Darth" and enjoyed a cult following. The dark lord classically sized 38.5mm diameter case is not only an early production of the Lange 1, but also an early example within the "Darth" series. This can be defined by the two hallmarks stamped on the caseback instead of 4 in later examples, as well as the absence of anti-reflective coating on the crystals like the present example. Ever since the first collection of the new era was presented in 1994, the LANGE 1 has been the face of A. Lange & Söhne. Reference 101.035 features a platinum case with a glazed caseback, showing the manually wound calibre L901.0 movement. It also features a jumping outsize date. It advances instantaneously by one day at midnight and therefore always delivers a doubt-free reading. Case: very good. Dial: as new. Movm.: as new, capable of running.

Los 42 - A. Lange & Söhne - LANGE 1 - A heavy and rare Glashuette wristwatch with Lange oversize date, 72h power reserve and still with screwed-on solid back. The watch was produced and sold in 1997. In 1997 only very few watches were still produced with the solid case back, which was replaced in 1996 by a transparent sapphire crystal back by customer and retailer request Movm. No. 3858, Ref. 101.001, Cal. L901.0, Case No. 113087, Dimensions 38,5 mm, circa 1997, Origin Deutschland, Extract from the archives, gold original clasp Case: 18 K gold, screwed on solid back, pusher at "10" for quick setting of the calendar. Dial: Solid silver, champagne. Movm.: Manual. Ever since the first modern collection was presented in 1994, the LANGE 1 has been the face of A. Lange & Söhne. This LANGE 1, reference 101.001 in a yellow gold case with solid caseback is powered by the specially developed manual wind calibre L901.0, which sets a benchmark in terms of quality. The watch also features a jumping outsize date, which jumps a day at midnight and always delivers a clear reading. When it launched in 1994, the LANGE 1 certainly broke the mould with the design of its dial. All indications are in peripheral positions, which gives the watch its distinctive appearance and at the same time ensures perfect readability, because none of the displays overlap. The design of the LANGE 1 follows a coherent principle: the centres of the subsidiary seconds dial, the main dial and the outsize-date display are at the corners of an isosceles triangle. The proportions of the outsize-date display are harmonious as well: they respect the rule of the golden ratio. Case: very good. Dial: very good. Movm.: very good, capable of running, cleaning recommended.

Los 43 - A. Lange & Söhne - ZEITWERK LUMINOUS "Phantom" - A heavy and extremely rare Glashuette wristwatch in near mint condition, with power reserve and digital time display - full set Movm. No. 81543, Ref. 140.035, Cal. L043.3, Case No. 191506, Dimensions 42 mm, circa 2011, Limited 043/100, Origin Deutschland, Original box, Original certificate, Accessories, gold original clasp Case: Platinum, sapphire glass screwed on back. Dial: Black, semi-transparent, power reserve indicator. Movm.: Manual. A. Lange & Söhne’s ZEITWERK model was introduced on the market in 2009 – a fascinating combination of modern craftsmanship with traditional art and beauty. The watch features the distinctive "time bridge" with jumping hour and minute numerals – a design modelled on the famous Five-Minute Clock Johann Friedrich Gutkaes created for the Dresden Semper Opera House. Lange’s typical outsize date also draws its inspiration from Gutkaes' concept. The jumping numerals mechanism of A. Lange & Söhne's ZEITWERK always delivers a precise reading of time because the discs advance instantaneously rather than in the creep mode. It consists of two minute discs and a large hour ring that occupies the entire diameter of the movement. All numerals are identical in size and arranged for natural left-to-right reading. The constant-force escapement assures the steady flow of power to the balance and, every 60 seconds, the precise switching of the numerals. A year after the launch of the ZEITWERK the ZEITWERK LUMINOUS was introduced as the first model of the Lumen range. The biggest challenge was capturing sufficient daylight to make the numerals visible for night reading. As the discs change rapidly (60 seconds for the minute disc, 10 minutes for the decimal figure, etc.) there was no time to recharge the luminous mass. The solution was to use a transparent smoky UV-transparent sapphire crystal. This dial charges the Super-LumiNova luminous material all day long and creates a fascinating glow in the dark. To achieve a harmonious appearance, a black coat covers the nickel silver bridge and creates an exciting contrast particularly at nights when the numerals glow green. This design has led to ZEITWERK LUMINOUS becoming known as the "Phantom". Case: very good. Dial: as new. Movm.: as new, capable of running.

Venus 175 TJ, Case No. 1073774, Dimensions 37 mm, circa 1966, Origin Schweiz, Accessories Case: 18 K gold, bidirectional rotating bezel, push back with Swiss patent engraving "Brevet 217012" (Adrien Schweizer, Pièce d'horlogerie permettant d'effectuer des opérations tachymétriques et télémétriques / timepiece for tachometric and telemetric operations). Dial: Silvered. Movm.: Manual. This example dating to approximately 1966 boasts a captivating, two-tone patinated, champagne-coloured dial with red accents that lends the timepiece a sportive yet elegant appeal. A first generation, pearled revolving bezel complete the elegant yet sportive image of this timepiece. The case has developed a beautiful patina as well as a rare gold oxide over the years, indicating that the watch has not been worn very often. The movement is engraved "WOG", an US-American import mark of the Wakmann Watch Co. Inc., the American importer of Breitling timepieces. The Breitling chronograph with integrated slide rule dates from the early 1940s and is viewed as predecessor of the Navitimer - it is, however, not an aviation chronograph. The backs of the Chronomat models from the 1960s were engraved with the 1942 patent number of the slide rule functionality, which permitted general calculations such as multiplication and division. Case: very good. Dial: very good. Movm.: very good, capable of running, cleaning recommended.

Like this watch it has distinctive features that are also present in Hahn’s pocket watches. The gilt brass movement has a very large balance with brass wheel and a cylinder escapement with rounded pallet face of the cylinder wheel teeth. The elaborate balance bridge is exquisitely ornamented. The watch features a stop function for the balance, which can be adjusted with a lateral lever. The scaling of the seconds display on the dial is unusual in steps of 108. Very little is known about Johann Georg Auch’s work for Philipp Matthäus Hahn. Johann Georg Auch called himself a watchmaker and after working for Hahn, he worked for his brother Johann Jacob in Ludwigsburg. In 1794 he lived and worked as mechanic and watchmaker in Ludwigsburg Circa 1800 Johann Georg moved to Öhringen, where he held a position as mechanic to the court of the Prince of Hohenlohe-Oehringen.

Between 1945 and 1965, it was considered the largest airline not only in Brazil, but in the whole of Latin America. The designation "G.C.T." = "Greenwich Civil Time" was originally introduced in America to bring some order into the somewhat confusing concept of time measurement: in nautical science 12 noon marked the end of the day, whereas in astronomical usage it was the start of that same day. In article VI of its resolutions the International Meridien Conference in Washington in 1884 expressed the hope that "as soon as may be practicable the astronomical and nautical days will be arranged everywhere to begin at midnight". So "GCT" was, in fact, the same as "Greenwich Mean Time" but with the day starting at midnight. One of the few protests against this suggestion came from the British Royal Navy, who used the abbreviation "GCT" for "Gunnery Control Tower" and expected this to lead to confusions. Case: very good, worn. Dial: very good, slightly oxydized. Movm.: very good, capable of running, cleaning recommended.

U.S. Army Corps of Engineers The history of the U.S. Army Corps of Engineers goes back to June 16, 1775, when the second Continental Congress created an army with a chief engineer and two assistants. General George Washington’s first chief engineer was Colonel Richard Gridley. Finally, in 1779 a separate Corps of Engineers was created by the American Congress. Since that day the Corps of Engineers has been involved in all U.S. military actions - from the American Revolution where it played a pivotal role in battles such as Saratoga and the final victory at Yorktown with the help of a number of French officers, until the modern day actions in Iraq. The U.S. Congress has charged the Corps of Engineers from its first day on with construction and works "of a civil nature". Throughout the 19th and 20th centuries the Corps of Engineers has been instrumental in overseeing the construction of coastal fortifications, lighthouses, dams and other heavy engineering projects as well as major harbor constructions. In the 19th century the Corps was responsible for the mapping of the majority of the American West and of the American navigational channels. The many diverse activities of the Corps called for a robust and accurate chronograph, which prompted the head of the U.S. Expeditionary Force in Bern to request that Vacheron Constantin produce a prototype for field use. The watch was to have a silver case, a white dial with luminous Arabic numerals and hands, and a simple chronograph movement without counter. Vacheron Constantin produced two prototypes and delivered them on May 8, 1918; an order for 5,000 pieces was issued the very same day. The original order stated that lots of 100 watches were to be delivered per month, or even 150-200 whenever available. A total of 3,289 watches was delivered between July 1918 and the end of 1919, so that the contract was considered to have been met. Vacheron Constantin archives indicate that the company also made wristwatches with silver cases and gold buckles for the Corps of Engineers. Case: very good. Dial: very good. Movm.: very good, capable of running, cleaning recommended.
