Chronomat 28 Stainless Steel - Diamond / Black MOP

In Context

At 28 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. At 8.4 mm thick it is about average for a modern wristwatch. The case back is closed, so the movement stays out of sight. 100 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.

A72310531G1A1 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black gloss dial with a stainless steel case.

SuperQuartz movement based on ETA 956.652 / F03.412.
