Constellation Master Chronometer Small Seconds 34 Sedna Gold / Diamond / Black / Bracelet

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. 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. 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.

131.55.34.20.61.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black sunburst dial with a sedna gold case. Introduced in 2021.

Self-winding movement with Co-Axial escapement. Certified Master Chronometer, approved by METAS, resistant to magnetic fields reaching 15,000 gauss. Free sprung-balance with silicon balance spring, automatic winding in both directions. Small Seconds display at 6H. 18K Sedna™ gold rotor and balance bridge and luxury finish with Geneva waves in arabesque.
