Seiko 5 7009-8331 Men’s Dress Automatic Vintage Watch, 1984

Long luminous baton markers define the matte black dial of the Seiko 5 watch from 1984, reference 7009-8331. A framed Spanish-English day-date display sits in a rounded 37 mm steel case with brushed planes and polished accents. The original folded-link bracelet has a secure fold-over clasp, and in-house automatic caliber 7009 powers the watch.

Matte black clarity and luminous batons

The dial has a matte black, non-sunburst finish that limits glare. Applied long baton hour markers contain luminous inserts and align with a precise minute track. The applied Seiko 5 emblem sits beneath 12.

The neatly framed day-date aperture at 3 includes Spanish-English day discs. Baton hour and minute hands mirror the markers with luminous strips, accompanied by a slim central seconds hand that sweeps smoothly across the face.

Rounded steel and articulated original bracelet

The stainless steel case measures 37 mm across and 42 mm from lug to lug. Brushed planes combine with polished accents in a rounded, slim profile that suits wear beneath a cuff. The recessed crown at 4 keeps the control close to the head.

The original Seiko stainless steel bracelet has folded links and a secure fold-over clasp. Its articulation gives a comfortable drape at the wrist, while the retained metal attachment continues the case’s cohesive appearance. Those proportions and finishes support the watch’s documented dress-ready character.

In-house 7009, water resistance and service

This automatic watch uses Seiko’s in-house caliber 7009, a movement operating at a model beat rate of 21,600 vibrations per hour, or 3 Hz. It powers central seconds and the bilingual day-date display.

Water resistance is part of the watch’s design; no numerical rating or current pressure-test result is documented.

The compact rounded case and non-reflective dial of this watch from the early-to-mid 1980s reflect the practical Seiko 5 approach. Its calendar, recessed crown and original articulated steel attachment keep the useful features together without a crowded face.

The used watch is carefully preserved, fully serviced and fully operational, retaining all its original components. It comes with a 12-month warranty, and worldwide shipping is available.
