Tank Must Small Quartz Stainless Steel / Silver

In Context

At 22 mm this is jewellery scale — a watch sized to be worn as an ornament rather than read across a room. The 6.6 mm case is genuinely slim and goes under a shirt cuff without argument. The case back is closed, so the movement stays out of sight, and the mineral crystal sits between the two — harder to scratch than plexiglass, easier to chip than sapphire. Rated to 30 m, it is protected against rain and splashes and nothing beyond that.

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.

WSTA0042 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver guilloche dial with a stainless steel case.
