The term is now widely used to describe this elegant rectangular silhouette. This Seiko is not a Cartier, but it echoes that rectangular spirit in a discreet and accessible Japanese interpretation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the dial blue or black?\u003c\/strong\u003e\u003cbr\u003eThe dial is a deep midnight blue with a finely grained texture. Depending on the light, it can appear almost black, then reveal its bluish reflections under direct illumination. This dark, shifting hue is part of the piece's charm and pairs well with a wide variety of outfits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the Seiko calibre 7830?\u003c\/strong\u003e\u003cbr\u003eThe 7830 is an analog quartz Seiko movement, launched in the late 1970s and renowned for its exceptional slimness. It notably equipped the brand's slim dress watches. Reliable and precise, it only requires periodic battery replacement, to be entrusted to a watchmaker, making it an easy movement to live with every day.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the case made of steel?\u003c\/strong\u003e\u003cbr\u003eYes, the case is made of stainless steel, brushed and polished. Unlike gold-plated models, there is no risk of plating wear: steel retains its appearance over time and can be repolished if necessary. Here, there are a few fine signs of wear, consistent with the age of the piece and disclosed with complete transparency.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this watch suitable for a man or a woman?\u003c\/strong\u003e\u003cbr\u003eIt is a Unisex piece. Its 27.5 mm wide rectangular case offers a balanced size, equally comfortable on a men's or women's wrist. Its dress-watch form and clean midnight-blue dial make it an elegant watch, both by day and in the evening.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the international delivery time?\u003c\/strong\u003e\u003cbr\u003eDispatch within 48 hours, international delivery within 3 to 5 days, insurance included.\u003c\/p\u003e\n\u003cp\u003e\u0026nbsp;\u003c\/p\u003e ","brand":"Seiko","offers":[{"title":"Default Title","offer_id":54037537947985,"sku":"891177 7830-5000","price":280.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/montre-seiko-tank-7830-5000-cadran-bleu-nuit-texture-1988-atelier-victor-1.jpg?v=1781731640","url":"https:\/\/ateliervictor.co\/en\/products\/vintage-seiko-tank-watch-textured-midnight-blue-dial-1988","provider":"Atelier Victor","version":"1.0","type":"link"}
