Perpetual Calendar Split-Seconds Chronograph 5204 White Gold / Olive

In Context

At 40.2 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 14.3 mm it is a tall case, and it will catch on a cuff. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 65 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

5204G-001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a green sunburst dial with a rose gold case. Beyond the time it carries a chronograph and a perpetual calendar.

The CHR 29-535 PS Q is Patek's split-second version of the CH 29-535 PS Q. It is Patek's first in-house split-seconds chronograph with perpetual calendar and it contains a total of 496 parts.

6 other watches in the library run the Patek Philippe CHR 29-535 PS Q.
