Minute Repeater Alarm Philippe Stern

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 14.2 mm it is a tall case, and it will catch on a cuff. 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.

1938P-001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black gloss dial with a platinum case. It was a limited edition. Beyond the time it carries a minute repeater.
