Seiko SQ, Ref. 8C23-8000, Cal. 8C23, Men’s Quartz Analog Vintage Watch, 1985

A vertically textured silver-white dial and German/English day wheel distinguish this Seiko SQ watch from 1985, reference 8C23-8000. Applied baton markers surround a framed day-date at 3, with polished hands above the fine grain. Quartz caliber 8C23 sits inside a 35 mm stainless steel case, joined to its original satin-finished integrated bracelet.

Silver-white grain and bilingual calendar

The dial’s subtle vertical texture gives the silver-white surface depth while preserving its clear layout. Applied baton hour markers accompany a framed day-date window at 3. The day wheel offers German and English, with DIE among the German markings.

Slim polished baton hour and minute hands are joined by a central seconds hand. Their straight geometry follows the restrained furniture, while the vertical grain provides a different direction of light across the dial. The clean handset and textured surface retain this mid-1980s watch’s understated appearance.

Integrated steel case, flush crown and satin links

The stainless steel case measures 35 mm in diameter and connects directly to the integrated bracelet. Its compact size and continuous attachment keep the presentation cohesive, with the dial’s minimal furniture remaining the visual focus.

The original polished crown sits at 3, flush with the case. Its smooth exterior has neither an external logo nor fluting, preserving the case’s spare profile.

The original stainless steel bracelet has wide, rounded links with a satin finish. B234B is marked on the end link, and a secure folding clasp carries the Seiko signature. The shape and finish of the links continue the integrated metal design around the wrist.

Quartz 8C23, quick-set calendar and condition

This quartz watch uses Seiko caliber 8C23, a battery-powered movement with quick-set day and date adjustment. The separate calendar correction is useful when setting the bilingual display, without advancing the hands through repeated full-day cycles. Its quartz operation does not require regular winding.

This used example is in excellent vintage condition, retaining its original case, dial, hands, crown and bracelet. It is fully serviced and fully operational, with a 12-month warranty included. Insured worldwide shipping is available.
