Seiko extra-thin steel: the Japanese dress watch with cushion case and Roman dial
This Seiko watch is a dress watch for both men and women, worn equally well by a man or a woman, of great sobriety. Its steel cushion case, square with very rounded corners, combines the softness of curves with the rigor of form. It measures 33mm (35mm with the crown) for a Lug-to-lug of 36.5mm and a thickness of only 6.4mm. A slim and elegant piece, made to slip under a cuff.
The white lacquered dial is of absolute purity. Twelve black Roman numerals run around it, without the slightest superfluous ornament: nothing but the sharp contrast of black on white. The SEIKO and QUARTZ signatures occupy the top of the dial, the small Seiko QZ logo the bottom. Two fine blackened baton hands and a matching seconds hand sweep across the whole, in the purest spirit of the classic dress watch.
Inside beats the Seiko 6431 calibre, an extra-thin three-hand dress quartz movement. Its slim construction allows the watch's 6.4mm 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 shipping.
On the wrist, the piece plays the card of the timeless classic. The polished steel and the white Roman dial create an ensemble of great clarity, highlighted here by an original black crocodile-effect leather strap. The Buckle pin buckle is not original. The 18mm Lug width leaves the choice of replacement straps wide open.
Three points to note
- The cushion case, square with rounded corners, softens the silhouette while retaining a structured look: an elegant and timeless design.
- The white dial with Roman numerals, entirely uncluttered, embodies the classicism of the dress watch: understated and perfectly legible.
- At 6.4mm thick, it is an extra-thin watch, slipping under a shirt cuff without the slightest inconvenience.

Frequently asked questions
What is a "cushion" case?
The cushion case, or "cushion," is a square case with very rounded corners, evoking the shape of a cushion. It softens the rigour of the square while retaining a structured and elegant appearance. It is a classic watchmaking shape, neither entirely round nor entirely carrée, which gives this Seiko its timeless character.
Is the Seiko 6431 caliber reliable?
Yes. The 6431 is an ultra-thin three-hand dress quartz movement, renowned for its reliability. Its maintenance is extremely simple: a battery change by any watchmaker is sufficient. The movement of this example has been checked by our watchmaker and is guaranteed for 1 year.
Is the case steel or plated?
The case is steel, a durable and resistant material that retains its lustre over time. Unlike gold-plating, steel presents no risk of plating wear: it is a robust and understated choice, perfectly suited to a dress watch intended for daily wear.
Is this Seiko water-resistant?
No. Water resistance is never guaranteed on a vintage watch: the original gaskets have aged, and the caseback pressure is no longer what it was on the first day. Avoid the shower, swimming pool, and sea. Simple contact with rainwater, however, does not pose any difficulty.
What wrist does a 33mm case suit?
With a diameter of 33mm and a Lug-to-lug of 36.5mm, this is the classic dress watch format: ideally worn on a slim to medium wrist, where it appears perfectly proportioned, and discreet under a cuff thanks to its 6.4mm thickness. That said, a watch is also a matter of style: depending on personal taste and the desired look, this piece can be worn equally well by a man or a woman, on all kinds of wrists. Size is only a guide, never a rule.
