Harmony Tourbillon Chronograph Pink Gold / Black numerals

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 12.81 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 is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 65 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 18,000 vph the seconds hand advances 5 times a second, the slower and more audible rate of an older design.

5100S/000R-B125 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver matte dial with a pink gold case. Introduced in 2016. Beyond the time it carries a chronograph and a tourbillon.

Manual wind chronograph movement with tourbillon escapement, launched in the Harmony collection in 2015.
