Royal Oak OffShore 25854 Perpetual Calendar Titanium / Silver

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse.

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.

25854TI.OO.1150TI.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver dial with a titanium case. Introduced in 2003. Beyond the time it carries a perpetual calendar.

Self-winding movement with chronograph and perpetual calendar complications. JLC ebauche; module by Dubois-Depraz.
