Seiko gold-plated: the rectangular dress watch with sunburst gold dial and integrated bracelet

This Seiko watch is an all-gold rectangular-shaped watch, unisex, worn equally well by a man or a woman. Its gold-plated rectangular case, with its clean, elongated silhouette, extends seamlessly into its bracelet, in a fluid and graphic integrated design, emblematic of the dressed-up luxury of the 1980s. It measures 25mm wide (26mm with the crown) for a Lug-to-lug of 32.8mm and a thickness of only 5.5mm. A slim, racy piece, made to slip under a cuff.

The gold dial is the piece's greatest asset. Its sunburst surface, brushed in rays radiating from the center, captures the light in a play of changing reflections, framed by an engraved border that forms a central cartouche. Two set stones, at 1 o'clock, add a touch of light beneath the SEIKO and QUARTZ signatures. Two fine black sword hands stand out elegantly against the gold background, in a minimalist and sophisticated design.

Inside beats the Seiko 7430 calibre, an extra-thin dress quartz movement. Its slim construction allows for the watch's 5.5mm profile. In practice, maintenance is limited to a battery change by any watchmaker. The movement of this example has been checked by our watchmaker and the battery replaced before shipment.

On the wrist, the piece displays discreet, sunlit luxury. The case and the gold-plated integrated bracelet, with fine striations, create a supple and continuous all-gold silhouette, highly representative of the Seiko style of the period. It is a watch that is both dressy and graphic, of great elegance. The original bracelet is adjustable up to 21cm.

Three points to note

• The sunburst gold dial, with its engraved border, is the true asset of the piece: a surface that shimmers depending on the light.
• The dial features two set stones at 1 o'clock; we cannot guarantee their exact nature, whether diamonds or imitation stones, without gemological expertise.
• The case and bracelet are gold-plated, not solid: they show light signs of wear, noted in full transparency.

Frequently asked questions

What is a sunburst dial?
A sunburst dial features a finely brushed finish in delicate rays extending from the center, like the rays of the sun. This texture catches the light and reflects it differently depending on the angle, bringing the dial color to life and making it shimmer. On this gold ground, the effect is particularly luminous and constitutes the watch’s main aesthetic appeal.

Are the stones on the dial diamonds?
The dial features two stones set at 1 o’clock. We cannot guarantee their exact nature without gemological expertise: they may be small diamonds or imitation stones, commonly used on this type of dress watch. We prefer to state this in full transparency rather than assert what we cannot certify.

What is an integrated bracelet?
An integrated bracelet is a bracelet whose design continues seamlessly from the case, forming a continuous and fluid silhouette. Highly fashionable in the 1980s, this construction gives the watch a design-led and unified look. On this Seiko, the finely ribbed gold bracelet perfectly follows the rectangular case.

Is the case solid gold?
No: this is a gold-plated case and bracelet over a steel base, a common construction on Seiko dress watches. The plating brings the warmth and radiance of gold for a fraction of its price. This piece shows fine signs of wear on its plating, disclosed in full transparency.

For what wrist is this watch suitable?
With a rectangular case 25mm wide and a bracelet adjustable up to 21cm, this is ideally a piece with a dressy, streamlined format. That said, a watch is also a matter of style: depending on personal taste and the look sought, it can be worn equally well by a man or a woman who appreciates shaped watches with a design-driven aesthetic. The indication is only a guide, never a rule.
