LadyMatic Co-Axial 34 Yellow Gold Diamond / Diamond Flower

In Context

At 34 mm it is classically proportioned: the size a dress watch was understood to be for most of the twentieth century, and small enough to sit under a cuff. At 11.95 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. 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. 50 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 25,200 vph the seconds hand advances 7 times a second.

425.67.34.20.55.005 stands on its own in this catalogue — no other reference here shares its base number. It pairs a white dial with a yellow gold case.

8521 sans date. Self-winding movement with Co-Axial Escapement for greater precision, stability and durability. Free sprung-balance system with silicon balance-spring. Automatic winding in both directions to reduce winding time. Oscillating mass and balance bridge in 18 Ct red gold. Luxury finish with exclusive Geneva waves in arabesque.
