Perpetual Calendar Chronograph 2499

In Context

At 37.6 mm it sits just under the modern norm — the band that suits the widest spread of wrists. The case back is closed, so the movement stays out of sight, and the plexiglass crystal scratches easily but polishes back out at home, which sapphire does not.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 42 hours of reserve carries it overnight, but not through a weekend in a drawer. At 18,000 vph the seconds hand advances 5 times a second, the slower and more audible rate of an older design.

2499J Series 3 is one of 3 executions of the 2499J base reference. Underneath they are the same watch; what separates this one is a silver dial and a yellow gold case. Beyond the time it carries a chronograph and a perpetual calendar.

Handwound chronograph movement with perpetual calendar based on a Valjoux ebauche.
