Millenary Openworked

In Context

At 47 mm this is exceptionally large for something worn on a wrist, closer to a pocket watch given lugs. At 13 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 20 m, it is protected against rain and splashes and nothing beyond that.

The movement winds itself from the motion of your wrist. 60 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.
