Royal Oak Offshore Tourbillon Chronograph Selfwinding Stainless Steel / Blue

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 14.45 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 winds itself from the motion of your wrist. 65 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

26540ST.OO.A027CA.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue dial with a stainless steel case. It was a limited edition. Introduced in 2017. Beyond the time it carries a chronograph and a tourbillon.

Selfwinding tourbillon chronograph movement developed by Renaud & Papi, launched in 2011. Total of 335 parts.
