Rotonde de Cartier 45 Day & Night White Gold / Silver

In Context

At 45 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 12.77 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 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.

W1556244 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver guilloche dial with a white gold case.

Self-winding movement with retrograde moon-phase and day & night indicator.
