High-polished yellow gold finish on the bezel and bracelet edges; likely vertical brushing on the dial face. Uniform warm yellow tone.

Gemstones & Inlays

None visible. Simple baton-style applied hour markers and stick hands.

Clasp & Closure

Fold-over jewelry clasp or sliding adjustable pressure clasp, typical of Seiko's vintage rectangular models.

Chain & Links

Integrated horizontal link bracelet, likely folded-link construction rather than solid links.

Craftsmanship Details

Precision-engineered movement; stamped links; electroplated finish. Robust mass-production quality designed for daily wear.

Authentication Indicators

Seiko logo typography, characteristic case back markings (visible upon inspection), and weight consistency with high-quality base metal alloys.

Origin & Maker

Japan; Seiko Watch Corporation. Known for high-quality mass production and reliability.

Era & Period

Late 20th Century (approx. 1980s-1990s). Stylistically influenced by the Cartier Tank aesthetic.

Age Estimate

Circa 1985-1995 based on the dial layout and bracelet style.

Cultural Significance

Represents the democratization of style; Seiko made the iconic 'Tank' look accessible to the general public with reliable, low-maintenance movements.

Condition Notes

Good; shows visible surface micro-scratches on the crystal and case. Plating appears intact but may show minor wear on high-friction points like the clasp.

Value Estimate

Market value $40–$120. Minimal gold value as it is electronic/base metal; value lies in brand reputation and vintage aesthetic.

Care & Maintenance

Gently wipe with a soft cloth. Avoid ultrasonic cleaning as the case may not be water-resistant. Keep away from perfumes and hairsprays which can erode plating.
