Its \u003cstrong\u003etonneau steel case\u003c\/strong\u003e, with curved sides and \u003cstrong\u003ecentral lugs\u003c\/strong\u003e — point attachments placed in the middle of the sides rather than at the corners — gives it an original and elegant silhouette, characteristic of the dress design of the 1980s. It measures 28.5mm wide (30.5mm with the crown), with a Lug-to-lug of 39mm and a thickness of only 6mm. An ultra-thin and refined piece, made to slip under a cuff.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003ewhite lacquered dial\u003c\/strong\u003e is one of pared-back classicism. \u003cstrong\u003eBlack Roman numerals\u003c\/strong\u003e run around its perimeter, surrounding a \u003cstrong\u003edouble minute track\u003c\/strong\u003e that forms a cartouche echoing the shape of the case. The SEIKO and QUARTZ signatures occupy the center, the small Seiko QZ logo the lower part. Two fine blackened baton hands are enough: no seconds hand, no date, only the essentials, in a design of great restraint.\u003c\/p\u003e\n\u003cp\u003eInside beats the \u003cstrong\u003eSeiko 7820 calibre\u003c\/strong\u003e, an ultra-thin two-hand dress quartz movement. Its slim construction allows the watch’s 6mm profile. In practice, maintenance is limited to battery replacement 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 \u003cstrong\u003etimeless classicism\u003c\/strong\u003e. The polished steel and white Roman dial create an ensemble of great clarity, highlighted here by a black \u003cstrong\u003egenuine crocodile leather\u003c\/strong\u003e strap. This strap is not original; it is fitted with a steel Buckle. The 17mm Lug width leaves the choice of replacement straps open.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThree points to note\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe tonneau case with central lugs is an original and sought-after design, characteristic of the dress elegance of the 1980s.\u003c\/li\u003e\n\u003cli\u003eThe white dial with Roman numerals and double minute track embodies the classicism of the dress watch: understated and perfectly legible.\u003c\/li\u003e\n\u003cli\u003eAt 6mm thick, it is an ultra-thin watch that slips 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 tonneau dress watch, central lugs, Roman dial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 7820-5480\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated year:\u003c\/strong\u003e 1989 \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 7820\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e Steel (steel back), tonneau shape with central lugs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 28.5mm (30.5mm with the crown)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug to lug:\u003c\/strong\u003e 39mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 6mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug width:\u003c\/strong\u003e 17mm\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, double railway minute track, Seiko and Quartz signatures, Seiko QZ logo, original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHands:\u003c\/strong\u003e Blackened batons (hours, minutes), original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal :\u003c\/strong\u003e Mineral, very fine condition (9\/10)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Genuine black crocodile leather, not original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuckle :\u003c\/strong\u003e Steel, not original\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCondition and guarantee\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeneral condition:\u003c\/strong\u003e Excellent state of preservation.

On this Seiko, it also features central lugs: the strap attachments are positioned in the middle of the upper and lower sides, rather than at the corners, giving the watch an original silhouette and a distinctly dressy character.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow was this watch dated?\u003c\/strong\u003e\u003cbr\u003eIts date was estimated from its serial number and calibre, according to the Seiko method: the first character of the number indicates the year, the second the month. Cross-referenced with the production period of calibre 7820, this places the piece in October 1989. This dating remains indicative, as the Seiko convention is not an official brand standard.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the case steel or plated?\u003c\/strong\u003e\u003cbr\u003eThe case is steel, a durable and hard-wearing material that retains its lustre over time. Unlike gold-plating, steel does not carry any 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, pool, and sea. However, simple contact with rainwater does not pose any difficulty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat wrist size does this watch suit?\u003c\/strong\u003e\u003cbr\u003eWith a tonneau case measuring 28.5mm wide and a Lug-to-lug of 39mm, this is ideally a shaped watch in a measured format, comfortable on a slim to medium wrist and easy to slip under a cuff. That said, a watch is also a matter of style: depending on taste and the look sought, this piece can be worn just as well by a man as by a woman, on all kinds of wrists. The market rating is only a guide, never a rule.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e ","brand":"Seiko","offers":[{"title":"Default Title","offer_id":54525120479569,"sku":"902320 7820-5480","price":1.05,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/seiko-7820-5480-tonneau-acier-cadran-blanc-romain-1989-atelier-victor-1.jpg?v=1787406941","url":"https:\/\/ateliervictor.co\/en\/products\/seiko-dolce-watch-7820-5480-steel-white-roman-dial-1989","provider":"Atelier Victor","version":"1.0","type":"link"}
