Cabestan, Winch Tourbillon Vertical, from a sponsorship contract, probably around 2008. A very impressive, innovative and futuristic trapezoid-shaped titanium watch in confidential production, a veritable showcase for an incomparable mechanical movement. Two separate thermoformed glass shells offer a 360-degree view of a vertical hand-wound mechanical movement with a fusee and chain system. Hours, minutes, power reserve and seconds read off on rotating drums, with the seconds fixed to the tourbillon, itself mounted in a vertical position. Transparent screw-down caseback, titanium folding clasp housing a glass compartment housing the winch for winding and setting the time. Winding and time-setting are performed via two separate crowns on the case middle, using the winch or a special tool supplied with the watch. Our working watch, with no defects other than tiny traces of supercifi cation, comes from a sponsorship contract with a racing driver. With no number on the case, it could be considered one of the very first watches to come out of the workshops for marketing purposes, or even a prototype. In 2008, production was scheduled at 4 pieces per month, with a customization program that made each of these watches unique or produced in very confidential numbers. The first prototype of the Winch Tourbillon Vertical was presented in 2007. When Vianney Halter gave up production of the watch, Eric Coudray, a former Jaeger-LeCoultre watchmaker who became famous for turning the Gyrotourbillon's spherical biaxial tourbillon, joined the project. The first examples are said to have appeared in 2008, with a price set at around CHF 200,000. "Exceptional aesthetics, incomparable mechanics" and "an assertive personality and a movement of rare ingenuity" were some of the headlines in the trade press when the watch was presented. The vertical constant-force movement, obtained by means of a fusee-and-chain system, would guarantee extremely precise chronometry, compensating for the disruptive effects of terrestrial gravity on watchmaking precision, all housed in a case with a resolutely innovative design. Dim 46 x 36 mm A very impressive, innovative, and futuristic trapezoid-shaped titanium watch made in a limited edition of 135 pieces, a true showcase of unparalleled mechanical movement. Two dissociated thermoformed glass shells offer a 360-degree view of a vertical manual winding mechanical movement, with a chain and fusée system. Digital indications of time in hours, minutes, seconds and power reserve on rotating drums, with the seconds indicated on the tourbillon, itself mounted vertically. Transparent screw-down back, titanium deployant buckle housing a glass compartment containing the winch for winding and setting the time. Our watch, working and without defects other than tiny superficial traces, comes from a sponsorship contract with a racing driver and would have come from production between 2008 and 2010. Without any case number, our watch could may be considered one of the very first watches to come from the workshops for marketing purposes, even maybe as a prototype. Monthly production was estimated in 2008 at 4 examples and offered a personalization program making each of these watches a unique example or produced in a very limited number. The first prototype of the Winch Tourbillon Vertical was shown in 2007. However, Vianney Halter abandoned production of the watch. This saw Eric Coudray, a former watchmaker of Jaeger-LeCoultre who became famous as the master who made the spherical biaxial tourbillon of the Gyrotourbillon watch rotate, join the project. The first examples are believed to have appeared in 2008, with a retail price around 200.000 CHF. "Exceptional aesthetics, unparalleled mechanics" or "a distinctive personality and a movement of rare ingenuity" were often mentioned in the specialized press during the watch's presentation. The vertical movement with constant force achieved through a fusee and chain system would provide the guarantee of extremely precise chronometry, compensating for the disruptive effects of Earth's gravity on timekeeping accuracy.
