Split-Seconds Chronograph 5959 Platinum / Black

In Context

At 33 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. 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.

5959P-011 is one of 2 executions of the 5959P base reference. Underneath they are the same watch; what separates this one is a black dial and a platinum 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.
