DESCRIPTION

LIMITED TO ONLY 300 PIECES WORLD-WIDE: PATEK PHILIPPE 5350R ADVANCED RESEARCH ANNUAL CALENDAR IN ROSE GOLD

A year after the launch of the first Swiss lever escapement with a silicon escape wheel (patent application No. EP05006186), Patek Philippe presents an additional fundamental innovation: the Spiromax balance spring made of Silinvar. It is an epochal step forward in the constant quest for isochronism in portable mechanical watches. On the occasion of Baselworld 2006, the Geneva workshops will showcase the first watch with this innovation in a second limited “Patek Philippe Advanced Research” edition: the Ref. 5350 with a Spiromax spring and a silicon escape wheel. Isochronism is the key to every measurement of time based on any form of vibration. The greater the regularity of the vibration, the better the movement can be adjusted to achieve a high rate accuracy. If the source of the vibration is perfect, it is called isochronous. exhibition case back inscribed “Patek Philippe Advanced Research” with cyclops magnifier over the silicon escape wheel

The first Patek Philippe watch with a Spiromax spring: the Ref. 5350 Annual Calendar in a limited “Patek Philippe Advanced Research” special edition A pioneering invention like the Spiromax spring deserves to be showcased. A second limited “Patek Philippe Advanced Research” edition of the self-winding Annual Calendar Ref. 5350 in 18K rose gold is therefore being launched on the occasion of Baselworld 2006. Its caliber 324 S IRM QA LU is the first movement fitted with a Spiromax spring made of Silinvar. As a further exclusive feature, it is also equipped with a silicon escape wheel. To do justice to these technical innovations, the movement has a specially shaped balance cock that reveals a large portion of the Spiromax spring and the going-train bridge is milled so that the mysterious blue-violet sheen of the nearly black silicon escape wheel is more readily visible. Additionally, the sapphire-crystal back has an integrated loupe and bears the inscription “Patek Philippe Advanced Research.” The solid 21K gold winding rotor features a zirconium ball bearing. Like the silicon escape wheel, the balls run dry and never need to be lubricated. The edition of this “Patek Philippe Advanced Research” model, the Ref. 5350R, is limited to three hundred watches.
