P-001 Perpetual Calender 5236 Platinum / Blue

In Context

At 41.3 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 11.07 mm thick it is about average for a modern wristwatch. 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.

5236 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue gradient dial with a platinum case.

Self-winding movement with perpetual calendar, whose main calendar indicators are all on the same plane. Total of 503 parts.
