The 6.5mm thickness remains restrained, and the very short, curved lugs keep the strap as close to the wrist as possible. The steel is mirror-polished across the entire caseband, with no brushed surface.\u003c\/p\u003e\n\n\u003cp\u003eThe creamy white dial bears twelve black Arabic numerals in a fine, slightly slanted design, following the curve of the oval. No markers, no minute track, no ornament: the numerals alone occupy the entire perimeter. The blued baton hands stand out crisply against it, accompanied by a very slender central seconds hand. A discreet golden emblem appears below the center, the dial’s only note of color.\u003c\/p\u003e\n\n\u003cp\u003eContrast is the subject of this watch. A cream dial, black numerals, blued hands, all set within a polished steel case: only four values, with no gradation or intermediate material. It is a design that owes more to jewelry than to watchmaking, where the watch is first read as an object worn before being read as an instrument.\u003c\/p\u003e\n\n\u003cp\u003eThe 1F21 calibre powering it is a ladies’ three-hand quartz movement, whose reduced dimensions — a little over ten millimeters by twelve — allow the full mechanism to fit within a case of this size. It runs on a 337 battery, one of the most common formats, which makes servicing simple anywhere in the world. It is fitted with a black leather strap made by hand.\u003c\/p\u003e\n\n\u003ch3\u003eThree points to note\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e21mm jewel format\u003c\/strong\u003e — a scale that few brands still offer today, supported by the renewed popularity of small women’s watches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBaignoire shape\u003c\/strong\u003e — an elongated oval with curved sides, a classic ladies’ watch silhouette that Seiko developed across its dress lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMirror-polished steel\u003c\/strong\u003e — a completely polished caseband, with no brushed surface, that catches the light across its full height.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy choose a vintage Seiko watch?\u003c\/h3\u003e\n\n\u003cp\u003eBuying a \u003cstrong\u003evintage women’s watch\u003c\/strong\u003e signed Seiko rather than a new model means gaining access to a leading Japanese manufacture at a controlled budget, through pieces whose construction has proven its durability.

It is shape-related vocabulary commonly used in française watchmaking, independently of any brand: it describes the geometry of the case and nothing else. This silhouette was long associated with ladies' watches, before returning to favor in recent years.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat wrist size is this watch suitable for?\u003c\/strong\u003e\u003cbr\u003eWith a case measuring 21mm wide, 33.5mm Lug-to-lug and 6.5mm thick, this is a strictly feminine format, suited to slim to medium wrists. The Lug width measures 12mm, which makes it easy to change the strap in a very common size. It can be worn on its own or paired with slim bracelets.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSteel or gold-plated, how to choose?\u003c\/strong\u003e \u003cbr\u003eWe offer this reference in both finishes. Steel pairs well with white Jewelry and is better suited to daily wear: it has no surface layer liable to wear away. Gold-plated offers a warmer, more dressy look, but requires greater care in areas subject to friction. It is as much a wardrobe choice as a matter of taste.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs a vintage Seiko watch a safe purchase?\u003c\/strong\u003e\u003cbr\u003eIt is, provided authenticity has been established and the condition is described without reservation. Our watchmakers systematically open the case to verify the calibre and its consistency with the reference, and inspect the dial, hands, and all components. Every pre-owned Seiko watch sold by Atelier Victor comes with an invoice serving as a certificate of authenticity, a one-year guarantee, and lifetime guaranteed authenticity.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs this watch water-resistant?\u003c\/strong\u003e\u003cbr\u003eWater-resistance is not guaranteed on a vintage piece. The original gaskets have aged, and we do not carry out pressure tests, as these could damage the case. We recommend avoiding any prolonged contact with water, including when washing your hands.\u003c\/p\u003e\n\n \u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"Qu'appelle-t-on une forme baignoire ?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"Le terme désigne un boîtier ovale allongé, dont les flancs se galbent doucement vers les cornes, par analogie avec la silhouette d'une baignoire vue du dessus.
