Its principle can be summed up in one word: slimness. Cases measuring thirty-two to thirty-five millimetres, thickness around five, a display reduced to the essentials, quartz movements. The word DOLCE is printed on the dial, above six o'clock.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the reference 8N40-6090 mean?\u003c\/strong\u003e\u003cbr\u003eSeiko references are read in two parts: the first, here 8N40, indicates the movement calibre; the second, 6090, the case code, engraved on the caseback. The dial bears a separate code, here 6170, which identifies the dial alone. The caseback takes precedence over the dial in establishing a piece's reference.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does this watch have only two hands?\u003c\/strong\u003e\u003cbr\u003eIt is a design choice typical of extra-thin dress watches: without a seconds hand, the dial remains uncluttered and the movement can do without the corresponding gear train, which helps keep the thickness to five millimetres. The time is read by the hours and minutes, as on a mantel clock.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the gold-tone bezel be refinished?\u003c\/strong\u003e\u003cbr\u003eWe do not recommend it and do not do it. A gold-tone finish is a thin layer applied to the metal: polishing it to remove scratches means removing it where it is still present, and the result ages less well than the original marks. It is preserved by avoiding water, household products and cosmetics, and cleaned with a soft, dry cloth.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does a 32mm case with a thickness of 5mm wear?\u003c\/strong\u003e\u003cbr\u003eThis format disappears under a shirt cuff without lifting it, which is exactly its purpose. At 36mm from top to bottom, it suits wrists of about 15 to 18cm — a guide, never a rule: everyone wears what they like. On a large wrist, it works as a deliberately discreet watch.\u003c\/p\u003e\n \u003cscript type=\"application\/ld+json\"\u003e\n{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Qu'est-ce que la ligne Dolce de Seiko ?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"C'est la ligne que Seiko consacre à la montre habillée, apparue au milieu des années 1980 et menée en parallèle des Grand Quartz.
