Traditionnelle Quartz Pink Gold / Diamond / MOP

In Context

At 30 mm it is small by current standards, in the range most wristwatches occupied before cases began growing through the 1990s. The 7.77 mm case is genuinely slim and goes under a shirt cuff without argument. 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. 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.

25558/000R-B156 stands on its own in this catalogue — no other reference here shares its base number. It pairs a white dial with a pink gold case.
