52 - Patek Philippe - Calatrava Amagnetic

Patek Philippe - Calatrava Amagnetic A highly elegant, antimagnetic vintage Geneva wristwatch Movm. No. 733601, Ref. 3420, Cal. 27-AM 400, Case No. 431965, Dimensions 34 mm, circa 1970, Origin Schweiz Case: 18 K gold, push back. Dial: Silvered, enamel scales and lettering. Movm.: Manual. Different to famous antimagnetic watches such as the Rolex Milgauss or the IWC Ingenieur, Patek Philippe’s reference 3420 is of a rather demure elegance and quite unostentatious. The 18-carat gold case is unpolished, with clearly visible gold hallmarks and is fitted with a domed acrylic glass. The bezel is slim and low-key enough to give the impression that the delicately shimmering dial sits directly on the wrist. The lettering and the seconds scale are engraved and enamelled in high relief. Reference 3420 was first produced in 1959 and fitted with calibre 12-400. Only a few of those were antimagnetic. In 1960 the antimagnetic calibre 27AM-400 was launched with a lever escapement made from beryllium bronze. Case: very good, slightly worn. Dial: very good. Movm.: very good, capable of running, cleaning recommended.
