Twenty~4 4909/107 White Gold / Diamonds

In Context

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. Its 38-hour reserve wants wearing most days; leave it off and it stops. At 28,800 vph the seconds hand advances 8 times a second.

4909/107G stands on its own in this catalogue — no other reference here shares its base number. It pairs a paved dial with a white gold case. It was a limited edition.
