Ricoh Quartz Diver 100M – Ref. 643018 – Day-Date – Vintage Japan

This rare Ricoh Quartz Diver is a Japanese vintage diver's watch with character and a unique appeal. The luminous dial in a very special cinnabar red immediately catches the eye, giving this watch an exceptionally strong presence. It is precisely this color that makes the model a true eye-catcher and provides that independent vintage character that is rarely found today.

Ricoh is one of the Japanese manufacturers that produced distinctive and technically interesting watches in the 1970s and early 1980s, but often fly under the radar today. This is precisely what makes such models exciting: they appear independent, unspent, and pleasantly stand out from the well-known classics of major mainstream brands.

Inside, the Ricoh Caliber 640, a battery-powered quartz movement with 17 jewels, is at work. The watch features a weekday and date display, with the weekday shown bilingually in English and Kanji – a nice detail with a typical Japanese connection. The battery has just been changed.

Visually, this watch also offers much of what makes a good vintage diver: a compact, robust case, a distinctive bezel, a very prominent dial design, and an overall wonderfully tool-like, authentic appearance. Thanks to the cinnabar red dial, it appears even more distinctive than many other vintage divers of its time.
