A rectangular Seiko Quartz from 1984, steel case with chamfered facets and original integrated steel bracelet, black dial with grey geometric decoration. Checked, new battery, delivered with its Atelier Victor invoice serving as a certificate.
A rectangular steel Seiko from 1984, geometric black dial and integrated bracelet
The rectangular case, 25 mm wide, is 6 mm thick. Its polished bezel, bevel-cut at the four corners, frames the Crystal like a mirror frame; the brushed sides of the case middle continue seamlessly into the original integrated steel bracelet. The steel caseback bears the piece's reference.
The black dial is printed with a grey geometric decoration: a central rectangle linked to the corners by radiating lines, like a perspective drawing. Four silver-tone baton markers, doubled at 12 o'clock, mark the quarters; the silver-tone dauphine hands and slender centre seconds stand out clearly. The Seiko Quartz signature is printed below 12 o'clock.
Calibre 7431 is a Japanese quartz movement with two jewels, three hands and no date. A new battery has been fitted. The serial number dates production to October 1984.
The original steel bracelet, with brushed links, closes with an original steel Buckle. The steel crown sits within the case middle at 3 o'clock. With 32 mm of Lug-to-lug, the watch can be worn on a man's wrist as well as a woman's wrist, as a dress piece in a restrained format.
Three points to note
01
Original geometric dial — A printed decoration of grey perspective lines on a black background, typical of the 1980s: no retouching.
02
Original integrated steel bracelet — Brushed links continuing from the case middle, original Buckle.
03
6 mm thick — A polished bezel with chamfered facets on brushed sides, slipping easily under a cuff.
Why choose a vintage Seiko Quartz watch from the 1980s?
In the 1980s, Seiko offered its quartz calibres in slim dress cases, often rectangular, with integrated bracelets and graphic dials. This reference 7431-5360, all steel with a geometric black dial, is one such expression from 1984, to wear daily as well as in the evening.

Frequently asked questions
Is the bracelet original?
Yes. The brushed-link steel bracelet and its Buckle are those of the watch; it integrates into the case middle with no visible lugs. Its length can be adjusted by removing links.
What does the dial decoration represent?
A geometric pattern printed in grey on a black background: a central rectangle and lines radiating toward the corners, in the graphic spirit of Seiko dials from the 1980s. We do not attribute to this piece any story that we cannot verify.
Has the battery been changed?
Yes. A new battery has been fitted; the movement is running. A quartz of this type does not require periodic maintenance beyond battery replacement.
Is this watch suitable for a woman's wrist?
Yes. At 25 mm wide, 32 mm Lug-to-lug and 6 mm thick, it wears equally well on a man's or a woman's wrist.
