Seiko 5 - Matte Black Dial

The dial is matte black—non-sunburst—so it reads perfectly in varied light. Applied baton hour markers carry luminous inserts, matched to a precise minute track for easy legibility. A neatly framed day-date window (Spanish/English discs visible) reinforces everyday practicality, while the applied Seiko 5 emblem under twelve anchors the design.

Seiko 5 7009-8331 - Hands

Baton hands mirror the markers and include luminous strips for dusk readability; a slim central seconds hand adds a clean sweep across the dial. The harmonious handset underscores the model’s dress-ready yet utilitarian ethos prized by Seiko enthusiasts.

Seiko 5 7009-8331 - Rounded Stainless Steel Case

The stainless-steel case blends brushed planes with polished accents, delivering subtle highlights without ostentation. At 37 mm across and 42 mm lug to lug, proportions suit a wide range of wrists. The rounded Seiko 5 profile from the early-to-mid 1980s wears securely while remaining elegantly slim under a cuff.

Seiko 5 7009-8331 - Crown

A recessed crown at the four o’clock position—a hallmark of the Seiko 5 concept—keeps the silhouette sleek and reduces the risk of accidental adjustments. It also enhances comfort for daily wear.

Seiko 5 Stainless Steel Bracelet

Paired with an original Seiko stainless-steel bracelet featuring folded links and a secure fold-over clasp, the watch achieves a cohesive, period-correct look. The bracelet’s articulation gives a comfortable drape while echoing the case finishing.
