Rotonde de Cartier Flying Tourbillon Pink Gold / Diamond / Silver

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. 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. 50 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.

HPI00593 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. Beyond the time it carries a tourbillon.

Hand-wound, Geneva Seal certified movement with tourbillon escapement. 142 parts including 19 jewels.
