Duomètre à Quantième Lunaire Pink Gold / Grey

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 13.5 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. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

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.

604244J stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey dial with a pink gold case. Introduced in 2017.

Caliber 381 is built upon the 'Dual-Wing’ concept, featuring two independent power reserves, one of which, in this case, is devoted solely to precise time measurement while the other takes care of the functional displays.

9 other watches in the library run the Jaeger-LeCoultre 381.
