Seamaster Aqua Terra 150M Quartz 38.5 Stainless Steel / Grey / Bracelet

In Context

At 38.5 mm it sits just under the modern norm — the band that suits the widest spread of wrists. 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.

It is quartz, so it will hold time far more closely than any mechanical watch here, and asks for a battery every few years rather than a service.

231.10.39.60.06.001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a grey dial with a stainless steel case. Introduced in 2013.
