Monopusher Chronograph 5470 Platinum / Blue

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 13.68 mm it is a tall case, and it will catch on a cuff. 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. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 36,000 vph the seconds hand advances 10 times a second, a high beat bought at the cost of faster wear.

5470P-001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue matte dial with a platinum case. Introduced in 2022. Beyond the time it carries a chronograph.
