A pure white dial, black numerals, blued hands, all set within an entirely golden case: only three values, without gradient or intermediate material.

It is a shape term commonly used in watchmaking française, 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\u003cp\u003e\u003cstrong\u003eThe dial indicates 1F21-1E20: is that the correct reference?\u003c\/strong\u003e\u003cbr\u003eYes. At Seiko, the code printed at the bottom of the dial is that of the dial itself, not that of the watch. The reference of the watch is engraved on the case back, here 1F21-5B70: the first group designates the caliber, the second the case. A discrepancy between the two codes is normal and is found on most Seiko.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow should a gold-plated case be cared for?\u003c\/strong\u003e\u003cbr\u003eThe plating is a layer of gold applied to a base metal, which thins over time in the areas most exposed to friction. A soft, dry cloth is sufficient for routine care; avoid abrasive products, perfumes, and household cleaners, which accelerate wear. On this watch, the signs of wear on the bezel are visible in our photographs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs quartz reliable on a watch from this period?\u003c\/strong\u003e\u003cbr\u003eYes. Seiko calibers from the 1990s are robust and easy to maintain: the battery — in one of the most common sizes in the world — is replaced every two to three years by a watchmaker, without the periodic servicing required by a mechanical movement. This one has been checked, fitted with a new battery, and is guaranteed for one year.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this piece suitable for a slim or larger wrist?\u003c\/strong\u003e\u003cbr\u003eAt 21mm wide, 33.5mm Lug-to-lug and 7mm thick, it is a jewelry-like format, intended for slim to medium wrists — a guideline, never a rule: everyone wears what they like. It can be worn alone or paired with slim bracelets, without ever crowding the wrist. The Lug width measures 12mm, which makes it easy to change the strap.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e ","brand":"Seiko","offers":[{"title":"Default Title","offer_id":54727890960721,"sku":"510361 1F21-5B70","price":1.05,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/montre-seiko-1f21-5b70-baignoire-plaque-or-chiffres-arabes-1995-atelier-victor-1.jpg?v=1788390560","url":"https:\/\/ateliervictor.co\/en\/products\/seiko-1f21-5b70-baignoire-watch-gold-plated-arabic-numerals-1995","provider":"Atelier Victor","version":"1.0","type":"link"}
