J-001 Minute Repeater Perpetual Calendar 3974 Yellow Gold

In Context

At 40.6 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.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 48 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.

3974 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver dial with a yellow gold case. Beyond the time it carries a perpetual calendar and a minute repeater.

Micro-rotor automatic movement with perpetual calendar and minute repeater. Total of 467 parts, hallmarked 'Geneva Seal'. Chime with two "cathedral" gongs activated by a slide piece in the case.
