The references all begin with 5E21, followed by the case code — here 6E00 — and the name is printed on the dial.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does a Crystal sapphire crystal offer?\u003c\/strong\u003e \u003cbr\u003eSapphire is the hardest of watch crystals: it resists the scratches of everyday life where a mineral crystal accumulates them, which explains the condition of the dial after nearly thirty years. It remains brittle under a sharp impact, and it cannot be polished: a damaged sapphire is replaced, not restored.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes a two-tone case require different care?\u003c\/strong\u003e\u003cbr\u003eYes, because of its two materials. The steel case middle can tolerate a slightly damp microfibre cloth. The gold-plated bezel, however, is a layer of gold over a base metal: it wears with friction and should be cleaned with a soft, dry cloth, never with an abrasive or a polishing paste, which would remove the layer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs a 16mm Lug width easy to replace?\u003c\/strong\u003e\u003cbr\u003eYes. 16mm is a common even size among bracelet and strap manufacturers, widely available in leather as well as metal. On a 30.5mm watch, it is also the width that preserves the proportions: a wider bracelet or strap would make the case look visually thicker.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this piece suited to a slim or larger wrist?\u003c\/strong\u003e\u003cbr\u003eWith a 30.5mm diameter, 35.5mm Lug-to-lug, and 5.4mm thickness, it sits well on wrists from about 14 to 18cm — a guide, never a rule: everyone wears what they like. Its slimness lets it slip under a shirt cuff without a second thought.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e ","brand":"Seiko","offers":[{"title":"Default Title","offer_id":54521266012497,"sku":"890669 5E21-6E00","price":367.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/montre-seiko-lucent-5e21-6e00-ronde-or-et-acier-cadran-blanc-1998-atelier-victor-7.jpg?v=1789616073","url":"https:\/\/ateliervictor.co\/en\/products\/vintage-lucent-5e21-6e00-watch-seiko-gold-and-steel-1998","provider":"Atelier Victor","version":"1.0","type":"link"}
