Overview

This is a classic Seiko 'Ana-Digi' quartz watch, a brilliant hybrid design that combined a traditional analog dial with a digital LCD readout. Encased in a sleek, rectangular stainless steel body, it represents a pivotal moment in horological history when mechanical tradition met the digital revolution.

Story

In the early 1980s, Japanese watchmakers led a global revolution by blending analog hands with digital screens. This dual-display design allowed jet-setters to easily track two time zones at once. It became the ultimate tech-chic accessory of its era.

Maker / Origin

Founded in 1881 by Kintaro Hattori in Tokyo, Seiko has been a relentless pioneer in timekeeping. They introduced the world's first quartz wristwatch in 1969, triggering the 'Quartz Crisis' that forever changed the Swiss watch industry and democratized precision timekeeping.

Condition & Value

The watch case shows minor surface scratches and wear consistent with age and daily use. The expansion band is an aftermarket addition. The functionality of the quartz movement and the digital LCD screen needs to be tested with a fresh battery; non-functioning electronics or battery leakage will reduce the value by 50% or more.

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
