Up for sale is an extremely rare vintage Seiko Quartz H557-506A men’s ana-digi dress/sports wristwatch, produced for the Japan Domestic Market (JDM) in the 1980s. This model features Seiko’s distinctive analog-digital layout combined with a bold, angular case and an integrated two-tone bracelet design, giving it a strong period-correct aesthetic and excellent wrist presence.

The watch appears to be in working condition. Timekeeping and digital display are functioning properly. I am unsure if the alarm/sound is working, as I have not been able to figure out how to set the alarm. Beyond this, no other issues are known.

All parts of the watch are original, including the case, dial, hands, and Seiko-signed stainless steel bracelet. The watch features a very unique case and bracelet design that is increasingly difficult to find in original configuration.

The watch shows signs of use and age consistent with its vintage nature, and the photos best describe its physical condition.
