Split-Seconds Chronograph 5950 Stainless Steel / Silver

In Context

At 37 mm it sits just under the modern norm — the band that suits the widest spread of wrists. 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. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

5950A-001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver dial with a stainless steel case. Beyond the time it carries a chronograph.

Ultra-thin mechanical manually wound movement with split-seconds function. Total of 252 parts. Patek's first in-house chronograph movement; debuted in the 2005 5959P.

11 other watches in the library run the Patek Philippe CHR 27-525 PS.
