Age Estimate

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.
