Royal Oak Concept Tourbillon Chronograph Yellow Gold / Rainbow

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 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. 237 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.

26235BA.YY.D502CR.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a skeleton dial with a yellow gold case. It was a limited edition. Beyond the time it carries a chronograph and a tourbillon.

Hand-wound movement with tourbillon escapement. Chronograph complication with linear minute counter. Function indicator for the crown position.
