Its rectangular \u003cstrong\u003ecushion case\u003c\/strong\u003e, with rounded corners, plays on the contrast between a steel case and a gold-plated bezel. It measures 27mm across (28mm with the crown) for a Lug-to-lug of 35mm and a thickness of only 6mm, Crystal included. A slender two-tone piece, made to slip under a cuff.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003esilvered dial\u003c\/strong\u003e reveals, in the light, a subtle sanded finish that breaks up the flatness of the background without ever bringing it to life. The hour markers are simple applied gilt batons, double at 12 o'clock. The SPIRIT signature occupies the top of the dial, the Seiko brand the center. Two gilt baton hands and a slender seconds hand complete a display that is as legible as it is understated. A pure design, entirely in service of the gold-on-silver contrast.\u003c\/p\u003e\n\u003cp\u003eBeating inside is the \u003cstrong\u003eSeiko caliber 5E31\u003c\/strong\u003e, an analog quartz movement from the 5Exx family that Seiko reserved for its extra-thin dress cases. It is precisely this slim architecture that allows the watch's 6mm profile. The movement of this example has been checked by our watchmaker and the battery replaced before shipping. Seiko did not publish a precision specification for this caliber: we therefore make no numerical claim.\u003c\/p\u003e\n\u003cp\u003eOn the wrist, the \u003cstrong\u003etwo-tone treatment\u003c\/strong\u003e gives the piece all its character. The gold-plated bezel warms the steel case, in a two-tone vocabulary that pairs just as well with a gold wedding band as with a steel signet ring. It is currently fitted with a khaki green \u003cstrong\u003egenuine crocodile leather\u003c\/strong\u003e strap that beautifully highlights the gilding. This strap is not original; it is mounted on a Buckle steel buckle. The Lug width of 18mm leaves complete freedom to change it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThree points to note\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe case is two-tone: gold-plated bezel and steel case. The bezel's gold plating shows fine scratches, disclosed here with complete transparency.\u003c\/li\u003e\n\u003cli\u003eNo original precision specification is published by Seiko for this caliber. We therefore make no claim as to seconds per month.\u003c\/li\u003e\n\u003cli\u003eThe bezel is gold-plated, not solid: avoid repeated rubbing against a bracelet or a belt buckle.\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\n→ \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 Spirit Tank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 5E31-5B50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEstimated year:\u003c\/strong\u003e 1994\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, Seiko 5E31\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 Two-tone, steel with gold-plated bezel (steel background), rectangular cushion shape\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 27mm (28mm with the crown)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug to lug:\u003c\/strong\u003e 35mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e 6mm (Crystal included)\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 Gold-plated, fluted, original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Sandblasted silver, applied gilt baton indexes, Spirit and Seiko signatures, original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHands:\u003c\/strong\u003e Gilt batons (hours, minutes), slender seconds hand, original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Mineral, very good condition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracelet:\u003c\/strong\u003e Genuine khaki green crocodile leather, non-original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuckle:\u003c\/strong\u003e Steel, non-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 Very fine state of preservation.

The two-tone cushion case belongs to the common vocabulary of dress watches from the 1980s and 1990s, adopted by many Japanese and Swiss houses. This piece claims to be nothing more than what it is, and the authenticity of its brand is guaranteed for life by Atelier Victor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the Seiko Spirit line?\u003c\/strong\u003e\u003cbr\u003eSpirit is a Japanese line of Seiko bringing together dress watches with a discreet and versatile spirit. It combines refined cases, worked dials and reliable quartz calibres, in a register halfway between a de ville watch and an everyday watch. This example is an extra-thin two-tone version with a sandblasted dial.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Seiko 5E31 calibre reliable?\u003c\/strong\u003e\u003cbr\u003eYes. The 5E31 is an analogue three-hand quartz movement from the 5Exx family, which Seiko reserved for its extra-thin dress cases. Its simple construction makes it durable, and in practice maintenance is limited to battery replacement. The movement of this example has been checked by our watchmaker and comes with a 1-year warranty.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this Seiko Spirit 5E31-5B50 water-resistant?\u003c\/strong\u003e\u003cbr\u003eNo. Water resistance is never guaranteed on a vintage watch: the original gaskets have aged and the pressure on the caseback is no longer what it was on day one. Avoid the shower, the pool and the sea. However, a simple exposure to rainwater does not pose any problem.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes a 27mm cushion case suit which wrist?\u003c\/strong\u003e\u003cbr\u003eOn a shaped watch, it is the Lug-to-lug that matters: 35mm here, which places the piece on wrists of around 15 to 18cm. The rectangular cushion format is the dress watch par excellence: discreet on a masculine wrist, perfectly proportioned on a feminine wrist. Its 6mm thickness allows it to slip under a cuff.\u003c\/p\u003e\n\u003cp\u003e\u0026nbsp;\u003c\/p\u003e ","brand":"Seiko","offers":[{"title":"Default Title","offer_id":54037523923281,"sku":"5E31-5B50 571385","price":315.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/VD_04467.jpg?v=1783890839","url":"https:\/\/ateliervictor.co\/en\/products\/vintage-seiko-tank-spirit-5e31-5b50-two-tone-sandblasted-dial-1994","provider":"Atelier Victor","version":"1.0","type":"link"}
