Royal Oak Concept 26580 GMT Tourbillon Titanium / White Ceramics

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 16.06 mm it is very tall, and sits high off the wrist. 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.

26580IO.OO.D010CA.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. Introduced in 2014. Beyond the time it carries a gmt and a tourbillon.
