Seiko Quartz 1979 — First impression - 7812-8039

The Seiko Quartz ref. 7812-8039 embodies late-1970s Japanese horology heritage with a minimalist aesthetic and an ultra-slim stainless-steel profile. The matte silver dial is crisp and glare-free, framed by a polished chapter ring and paired with fine baton markers for excellent legibility. A neatly bevelled date window at 3 o’clock enhances daily practicality without disturbing the dial’s symmetry. Thanks to the thin quartz movement, the watch sits close to the wrist and slips easily under a cuff, making it a refined choice for business or formal wear. Measured at 33 mm across and 38 mm lug-to-lug, it wears compact yet purposeful, showcasing Seiko’s precision timekeeping philosophy and design restraint of the period.

Seiko Quartz - Matte Silver Dial

The dial has a uniform matte silver finish—no sunburst effect—accented by slim black hour markers and a framed date at 3. The printing is clean and period-correct, with SEIKO and QUARTZ at 12. The overall presentation is understated, leaning into functional elegance prized by collectors.

Quartz 7812-8039 - Hands

Stick hour and minute hands in black deliver strong contrast against the dial, while the central seconds is rendered in subtle grey. The trio preserves the watch’s crisp, instrument-like clarity and aligns with the minimalist language of Seiko’s late-1970s quartz design.

Seiko Quartz 7812-8039 - Thin Stainless-Steel Case

The stainless-steel case combines a satin-brushed upper surface with a polished, slightly bevelled bezel for a discreet play of light. At 33.0 mm across and 38.0 mm lug-to-lug, it offers excellent comfort and versatility. The thin profile—enabled by the quartz caliber—enhances wearability under tailored sleeves.

Quartz 7812-8039 - Crown

A small polished crown sits at 3 o’clock and appears original to the watch head. Its discreet size preserves the clean case lines while remaining practical for quick date setting and time adjustments.

Seiko Quartz Leather Strap

The watch is fitted with a brown leather strap with contrasting stitch near the lugs. It is an aftermarket replacement chosen to complement the dial’s silver tone and the watch’s vintage character, delivering immediate comfort and everyday practicality.
