Beautiful and yet understated timepiece from ca. 1959 by Vulcain. Founded in 1858, the workshop of the Ditisheim brothers – which was to give rise to the Vulcain brand – immediately earned itself an enviable reputation through its complication watches, which received awards at several World Fairs. It does offer you an affordable way to buy an high class automatic movement, and full calendar with moonphase! It is powered by Felsa 693, a great movement featuring patented Bidynator technology allowing the barrel to be wound while rotor moves in both directions. Unpolished gold plated case. Fully-functional and keeping time perfectly. Case diameter without crown 34 mm used leather strap 22 cm lengh The caliber Felsa 693, also called Bidynator, is the first automatic caliber with both sides acting flywheel rotor. A mechanical switch on gear-based polarized at the 1942 created movement the direction of movement of the flywheel. When Rolex had blocked the overall market for these automatic moon phase calibers with the registration of its own patent on a triple calendar automatic movement, which has been issued as a self-development of Rolex, but in reality only a copy of the much earlier existing caliber AS 1402 N Adolph Schild S.A., Felsa brings additional sophistication supplement. Felsa founded in 1918 and 1928 is divided into the Ebauches Felsa AG, Lengnau (Canton of Bern), bypass the legal obstacles. In 1942 launched caliber Felsa 692/93 (11 1/2 lines, height 5.8 mm) caused a "switch" to gear based on the polarization of the rotor movement. The winding was therefore made in both directions of rotation of the flywheel mass. So do not miss the price rocket, prizes that will break records on the vintage watch market in the future.
