Railmaster Omega Co-Axial Master Chronometer Small Seconds 38 Stainless Steel / Beige Gradient / Bracelet

In Context

At 38 mm it sits just under the modern norm — the band that suits the widest spread of wrists. At 12.36 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 150 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. 60 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.

235.10.38.20.13.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a beige gradient dial with a stainless steel case. Introduced in 1957.

Self-winding movement with Co-Axial escapement and small seconds. Movement and watch tested according to Master Chronometer certification process approved by METAS. Resistant to magnetic fields reaching 15,000 gauss. Free sprung-balance with silicon balance spring, automatic winding in both directions. Rhodium plated finish with Geneva waves in arabesque. Power reserve: 55 hours
