Condition

The watch remains in good vintage condition with honest signs of age consistent with careful ownership. The stainless steel case retains its sharp geometric lines and brushed finish, while the original vertically textured dial remains well preserved. The crystal shows light surface scratches that do not significantly affect readability. A replacement leather strap has been fitted, complementing the watch’s clean minimalist design.

Notes

This vintage Seiko is a wonderful example of the clean, modern aesthetic that emerged from Japanese industrial design during the early quartz era. Rather than relying on decorative elements, it lets proportion, texture, and precision speak for themselves. The angular square case, brushed steel finish, and slim baton markers create a minimalist design that feels remarkably contemporary even decades after its production.

The standout feature is its beautifully executed engine-turned vertical dial texture. Often overlooked at first glance, the finely machined pinstripe pattern adds depth and visual interest by catching light differently across the dial without compromising its understated appearance. It’s the kind of subtle craftsmanship that rewards a closer look.

Another fascinating detail is the 5-jewel quartz movement inside. While many people associate jeweled movements exclusively with mechanical watches, Seiko incorporated jeweled bearings into many of its higher-grade quartz calibers to reduce friction and improve long-term reliability. Combined with production by Suwa Seikosha, one of Seiko’s historic manufacturing divisions responsible for many of the company’s most respected innovations, this watch reflects an era when Seiko treated quartz watchmaking as a showcase of engineering rather than simply a cost-saving technology.
