Constellation Co-Axial 38 Day-Date Stainless Steel / Black

In Context

At 38 mm it sits just under the modern norm — the band that suits the widest spread of wrists. 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. 55 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.

123.10.38.22.01.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a stainless steel case. Beyond the time it carries a day-date.

Self-winding movement with Co-Axial Escapement for greater precision, stability and durability. Day-date change at midnight with instantaneous jump. Silicon balance-spring on free sprung-balance, 2 barrels mounted in series, automatic winding in both directions to reduce winding time. Rhodium-plated balance bridge and oscillating mass, luxury finish with exclusive Geneva waves in arabesque.
