Seiko Quartz vintage: a gold-plated dress watch with a chocolate dial
This vintage Seiko Quartz watch is an elegant dress piece with a square gold-plated case, slim and understated, featuring a deep chocolate brown dial. With refined minimalism — only two hands, with no superfluous details — it embodies the discreet elegance of Japanese dress watches from the 1980s. In a versatile size, it wears equally well on a man’s or a woman’s wrist. A sober and distinguished piece, ideal for everyday wear as well as for evening occasions.
The chocolate brown dial, deep and luminous, embraces purity: an applied gold index at 12 o’clock, the « Seiko Quartz » signature and the discreet SQ emblem. Fine, slender gold hands sweep across the dial, for a clear reading in complete sobriety. A dark, warm dial, rare and elegant, in the great tradition of dress watches.
This Seiko is powered by the 7820 quartz calibre, a “high grade” movement renowned for its great finesse, which equipped Seiko’s extra-thin dress watches in the 1980s. Battery-powered, it perpetuates the legacy of Seiko, pioneer of quartz with the 1969 Astron. A controlled movement, guaranteeing precise daily operation, without demanding mechanical maintenance.
With its 28mm case, very slim profile (6.3mm) and carrée gold-plated shape, this vintage watch offers an elegant and versatile size, on the wrist of a man or a woman — a true Unisex watch. The dial and original hands are in excellent condition, as is the mineral Crystal (9/10). It is delivered on a genuine handmade crocodile leather strap, non-original, with a steel pin Buckle.

Frequently Asked Questions
What is a square-formed watch or a "carrée" shape?
The square form, close to the "Tank" silhouette popularized by Cartier at the beginning of the 20th century, refers to a case with clean, straight lines. Very much in vogue on dress watches, it brings a classic and refined look. This piece is not a Cartier: it is a Seiko, a Japanese manufacturer, which captures the spirit of a dress watch.
What is the caliber of this Seiko Quartz?
It is fitted with the Seiko 7820 quartz caliber, a high-grade movement from the 1980s, renowned for its great finesse, which powered extra-thin dress Seiko watches. Battery-powered, it ensures precise everyday timekeeping without mechanical maintenance.
Is the case solid gold?
No. It is a gold-plated case on a steel base. This dress finish offers the radiance of gold with the robustness of steel, and contributes to the elegant character of this vintage watch.
Is this Seiko watch vintage?
Yes. Dated from the 1980s, it is approaching forty years old. It is an authentic vintage Seiko watch, a testament to Japanese expertise in quartz dress watches.
Is this watch suitable for a man or a woman?
It is a Unisex watch. Its 28mm square case suits both a masculine and feminine wrist. Its minimalist chocolate dial and dress format make it an elegant watch for every occasion.
