Rotonde de Cartier Second Time Zone Day / Night Pink Gold / Silver

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11.96 mm thick it is about average for a modern wristwatch. 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 winds itself from the motion of your wrist. 48 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.

W1556240 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver dial with a pink gold case.

Self-winding, caliber 1904 with small seconds, with added module for big date, retrograde second time zone (12H) and day/night indicator.
