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 12.6 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 winds itself from the motion of your wrist. 70 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.
26439NB.OO.A346KB.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue matte dial with a ceramic, white gold case. Beyond the time it carries a chronograph.
