Minute Repeater Split-Seconds Chronograph Perpetual Calendar Platinum / Rose / Tokyo 2023

In Context

At 42 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 winds itself from the motion of your wrist. 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.

5308P-010 stands on its own in this catalogue — no other reference here shares its base number. It pairs a rose matte dial with a platinum case. It was a limited edition. Introduced in 2023. Beyond the time it carries a chronograph, a perpetual calendar and a minute repeater.

Self-winding mechanical movement. Minute repeater. Instantaneous perpetual calendar. Split-seconds chronograph. 60-minute and 12-hour counters. Moon phases. Small seconds. Diameter: 32 mm. Parts: 799.
