Its \u003cstrong\u003esteel cushion case\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003ewhite lacquered dial\u003c\/strong\u003e is of absolute purity. Twelve \u003cstrong\u003eblack Roman numerals\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eInside beats the \u003cstrong\u003eSeiko 6431 calibre\u003c\/strong\u003e, 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.\u003c\/p\u003e\n\u003cp\u003eOn the wrist, the piece plays the card of the \u003cstrong\u003etimeless classic\u003c\/strong\u003e. The polished steel and the white Roman dial create an ensemble of great clarity, highlighted here by an original black \u003cstrong\u003ecrocodile-effect leather\u003c\/strong\u003e strap. The Buckle pin buckle is not original. The 18mm Lug width leaves the choice of replacement straps wide open.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThree points to note\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe cushion case, square with rounded corners, softens the silhouette while retaining a structured look: an elegant and timeless design.\u003c\/li\u003e\n\u003cli\u003eThe white dial with Roman numerals, entirely uncluttered, embodies the classicism of the dress watch: understated and perfectly legible.\u003c\/li\u003e\n\u003cli\u003eAt 6.4mm thick, it is an extra-thin watch, slipping under a shirt cuff without the slightest inconvenience.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e→ \u003ca href=\"\/en\/collections\/montres-seiko-vintage\"\u003eDiscover our vintage Seiko watches\u003c\/a\u003e\u003cbr\u003e→ \u003ca href=\"\/en\/collections\/montres-vintage-moins-500\"\u003eSee our vintage watches under €500\u003c\/a\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Seiko\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Cushion dress watch, Roman dial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 6431-5040\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated year:\u003c\/strong\u003e 1982\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Japan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGender:\u003c\/strong\u003e Men's and women's watch (Unisex)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Japanese quartz, calibre Seiko 6431\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, seconds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e Steel (steel back), cushion shape\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 33mm (35mm with the crown)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug to lug:\u003c\/strong\u003e 36.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 6.4mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug width:\u003c\/strong\u003e 18mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Steel, original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e White lacquered, black Roman numerals, Seiko and Quartz signatures, Seiko QZ logo, original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHands:\u003c\/strong\u003e Blackened batons (hours, minutes), fine seconds hand, original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Mineral, in very good condition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e  Black crocodile-style leather, original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuckle:\u003c\/strong\u003e Pin buckle, not original\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCondition and warranty\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall condition:\u003c\/strong\u003e Excellent state of preservation.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Seiko 6431 caliber reliable?\u003c\/strong\u003e\u003cbr\u003eYes. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the case steel or plated?\u003c\/strong\u003e\u003cbr\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this Seiko water-resistant?\u003c\/strong\u003e\u003cbr\u003eNo. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat wrist does a 33mm case suit?\u003c\/strong\u003e\u003cbr\u003eWith 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.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e ","brand":"Seiko","offers":[{"title":"Generic","offer_id":54511088075089,"sku":"230358 6431-5040","price":378.0,"currency_code":"EUR","in_stock":true},{"title":"Seiko vintage","offer_id":54511088107857,"sku":"230358 6431-5040 + box","price":409.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/montre-seiko-6431-5040-acier-coussin-cadran-romain-1982-atelier-victor-1.jpg?v=1787406217","url":"https:\/\/ateliervictor.co\/en\/products\/seiko-6431-5040-watch-steel-cushion-roman-dial-1982","provider":"Atelier Victor","version":"1.0","type":"link"}
