Story

The late 1980s saw a dramatic return to analog elegance after the digital-heavy aesthetic of the early decade. This Seiko model was crafted to be the ultimate 'under-the-cuff' companion, prioritizing a slim profile that could transition from the boardroom to a formal gala.

Maker / Origin

Founded in 1881 by Kintaro Hattori in Tokyo, Seiko—which translates to 'exquisite' or 'success'—is the company that famously triggered the 'Quartz Revolution.'

Condition & Value

The crystal shows light surface scratching consistent with age, and there is minor wear to the gold plating on the lugs. The orange strap is a non-original replacement. The value assumes the movement is in working order with a fresh battery. Excellent condition with an original box would command a premium.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

▲ Strong maker attribution with credible period details
▲ Better-than-average condition for the category
▲ Broader demand rises when presentation and finish feel intact

Concerns

▼ Decorative-only demand limits the ceiling
▼ Surface wear or missing provenance can compress the range fast
▼ Regional sale lanes often underperform specialist venues
