HANDS Original


Signed on the dial, case and movement. DIAM. 65 mm. THICKNESS 19 mm. The present watch, adjusted by U. BRAHIER (as well as the TOURBILLON NO. 464262, Lot 166) was submitted to the GENEVA OBSERVATORY in 1968. It was one of a special group of watches, all with tourbillon regulators, and all adjusted under the direction of master adjuster E. OLIVIER AND BRAHIER, for the 1946 and 1947 Geneva Timing Contest. The results surpassed all expectations: the first three places in 1947 were taken by VACHERON CONSTANTIN, and the alltime record was broken,with 883.8 points. In particular, the record that Patek Philippe had held for 13 years, since 1934, was broken. Out of the 30 first places, Vacheron Constantin took half the prizes. All the watches were identical - extremely high-grade tourbillon regulators, made entirely in the factory, superbly adjusted by Olivier or Brahier, aided by the skill acquired through years of experience. Provenance: Crott & Schmelzer, October 1980.
