This elegant timepiece embodies the technical perfection and minimalist luxury of the late 1980s. This Seiko Quartz, reference 9021-5310, is defined by its classic rectangular "Tank" style case and a beautiful gold-plated finish. This style was highly popular for premium dress watches, signaling sophisticated taste and reliable precision. The dial is uncluttered, featuring simple gold-toned baton indices and a refined, two-hand display (no seconds hand), achieving a pure, elegant aesthetic.

The movement inside is the dependable Seiko Caliber 9021, a high-quality quartz engine that provides excellent grab-and-go accuracy that was a hallmark of Japanese Domestic Market (JDM) precision. This compact movement allows the case to be exceptionally slim and discreet on the wrist- a key characteristic of a luxury dress watch. The case back confirms the BASE METAL construction with a ST. STEEL BACK, common for these period-correct, slim, gold-toned watches. The serial number suggests a production date of February 1987 (722191), placing it at the zenith of the premium quartz dress watch era.
