Patek Philippe Ladies’ Chronograph Ref. 7150/250R-001 Hands-On

Patek Philippe introduced its first in-house integrated chronograph Caliber CH 29-535 PS in a ladies' watch, the Ref The movement will forever be remembered as the ladies' chronograph That first model is now discontinued in favor of a completely redesigned ladies' chronograph, the Patek Philippe Ref.

No matter how much I liked the 7071 with its round dial in a cushion shaped case, I couldn't help but think of the Vacheron Constantin Harmony Chronograph There is no such similarity with the new Patek Philippe Ref The profiles of the teeth on the wheels of the gear train were optimized to eliminate any lingering jump in the chronograph start/stop functions.

A split-seconds lever with a ruby roller between two flat heart cam shoulders keeps the chronograph and split-seconds hands precisely aligned. . Source
