Perpetual 1908 39 White Gold / Black

In Context

At 39 mm it sits just under the modern norm — the band that suits the widest spread of wrists. At 9.5 mm thick it is about average for a modern wristwatch. 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. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist. 66 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

52509-0002 is one of 2 executions of the 52509 base reference. Underneath they are the same watch; what separates this one is a white matte dial and a white gold case. Introduced in 2023.

Rolex Caliber 7140 is self-winding movement with small seconds. It features a Syloxi hairspring in silicon with patented geometry and high-performance Paraflex shock absorbers
