Royal Oak Offshore Perpetual Calendar Titanium

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 15.9 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. Its 38-hour reserve wants wearing most days; leave it off and it stops. At 28,800 vph the seconds hand advances 8 times a second.

26209TI.OO.D101CR.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a titanium case. It was a limited edition. Beyond the time it carries a perpetual calendar.

Modular automatic (cam-operated) chronograph movement with perpetual calendar. Total of 436 parts, including 50 jewels.
