Seamaster Aqua Terra 150M Master Co-Axial 30 Moonshine Gold - Diamond / MOP - Diamond / Bracelet

In Context

At 30 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. At 10.7 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. 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. 48 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.

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

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. Date display at 6H. 18K Sedna™ gold rotor and balance bridge and luxury finish with Geneva waves in arabesque.
