Royal Oak Offshore Tourbillon Chronograph Openworked Ceramic / Rubber

In Context

At 44 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 14.43 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. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 72 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

26407CE.OO.A030CA.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a skeleton dial with a titanium, ceramic case. It was a limited edition. Beyond the time it carries a chronograph and a tourbillon.

Handwound column wheel chronograph movement with tourbillon escapement. Total of 296 parts, including 28 jewels. Introduced in 2017.
