Ricoh Riquartz 580-510
Although Ricoh isn't as frequently featured in vintage Japanese watchmaking as Seiko and Citizen, it produced quite distinctive models, especially during the rise of quartz technology. The Riquartz series was one of the brand's important collections from this period.

In this example, the first detail that catches the eye is undoubtedly the blue sunburst dial. The surface, which changes from a dark navy blue to a very vibrant blue depending on the angle of the light, is complemented by simple steel indices, thin hands, and a framed date window. The fact that the day indicator can be used in Japanese Kanji and English is a nice period detail that preserves the watch's Japanese market identity.
Case and Bracelet
The 36 mm diameter stainless steel case features the characteristic integrated bracelet concept of the period. The straight and angular lines of the case continue directly to the bracelet, while the polished bezel surrounds the dial, adding a distinct contrast to the design.
The original Ricoh steel bracelet is also an important part of the watch's design. The central section, consisting of small links, is not only a visual detail; it also ensures that the bracelet sits more comfortably on the wrist.
Dial and Condition
One of the watch's strongest points is its state of preservation. The blue dial has beautifully retained its vibrancy and sunburst texture. The original blue protective film is still in place on the indices, hands, logo, and case back. The Riquartz markings are clean; the case and bracelet clearly indicate that the watch has never been worn.
Box, Papers, and Period Label
What sets this example apart from an ordinary Riquartz is the period pieces that have survived with the watch.
The watch comes with a Ricoh box, a Japanese Riquartz instruction manual, and the original period label with Ref. 580510. The label also bears the inscription ¥25,000. Since these small pieces of paper and documents related to the watch are often lost over the years, especially with vintage Japanese watches, the fact that they have been preserved together makes the set even more appealing.
Final Thoughts
It's not just one detail that makes the Riquartz 580-510 special; it's the fact that the pieces are still together.
Vibrant blue dial, Kanji day display, integrated Ricoh bracelet, protective film on the case back, box, booklet and period tag… Today we are able to offer this watch not only as a beautifully preserved Ricoh, but also as a highly complete set from its era.
