Its bezel is built in a double step: a first raised level frames the piece, while a second recessed level descends toward the dial. This break creates a permanent shadow line around the dial and gives the case a depth that its slim 6.2mm thickness would not suggest.\u003c\/p\u003e\n\u003cp\u003eThe silver-toned dial features a smooth satin finish that catches the light in a continuous gradient, from bright to grey depending on the angle. The hour markers are reduced to simple printed batons, longer at the cardinal points, with no applied markers or numerals. Steel baton hands and a very fine seconds hand complete the ensemble. The signature is limited to \u003cem\u003eSEIKO QUARTZ\u003c\/em\u003e beneath twelve o'clock, and to the \u003cem\u003eQ\u003c\/em\u003e emblem accompanied by its lightning pictogram at six o'clock.\u003c\/p\u003e\n\u003cp\u003eThe steel bracelet is integrated into the case and constructed from offset brick-style links, whose alternating brushed and polished surfaces create a checkerboard pattern along the entire length. This is not an added interchangeable bracelet: the continuity between the case middle and the first links is complete, in keeping with the principle that Seiko then applied to its upper ranges.\u003c\/p\u003e\n\u003cp\u003eThe 7830 calibre powering it is a three-hand analogue quartz movement, whose slim architecture allows for this thickness. The late 1980s corresponded, for Seiko, to a period of maturity in these movements: the technology had been mastered for twenty years, and the focus was then on the slimness of the cases and the quality of the finishing.\u003c\/p\u003e\n\u003ch3\u003eThree points to note\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-stepped bezel\u003c\/strong\u003e — a recess that creates a permanent shadow line around the dial and gives depth to the case.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated bracelet with offset links\u003c\/strong\u003e — a checkerboard of brushed and polished surfaces, in complete continuity with the case middle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6.2mm thick\u003c\/strong\u003e — a profile that few dress watches achieve, including among contemporary Swiss productions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy choose a vintage Seiko watch?\u003c\/h3\u003e\n\u003cp\u003eBuying a \u003cstrong\u003evintage Seiko watch\u003c\/strong\u003e 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.

On this piece, a first raised level frames the case and a second, set back, descends toward the dial. This step creates a permanent shadow line that highlights the dial and gives the case a visual depth that its slim thickness would not suggest.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the bracelet be adjusted?\u003c\/strong\u003e\u003cbr\u003eYes, it can be adjusted by removing links and currently measures 20cm. The procedure is carried out by a watchmaker, and we can take care of it before shipping if you let us know your wrist size. Please note that this is an integrated bracelet, whose attachments were designed for this specific case: it cannot be replaced with a standard strap with lugs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the Q emblem on the dial?\u003c\/strong\u003e\u003cbr\u003eIt is the logo that Seiko used on its quartz productions, accompanied by a lightning-bolt pictogram. At a time when the technology was still a distinguishing feature, the brand wanted to signal it visually on the dial. Today, this logo is an immediate dating marker for collectors.\u003c\/p\u003e \n\u003cp\u003e\u003cstrong\u003eIs a vintage Seiko watch a safe purchase?\u003c\/strong\u003e\u003cbr\u003eIt is, provided that 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\u003cp\u003e\u003cstrong\u003eIs this piece suitable for a slim or larger wrist?\u003c\/strong\u003e\u003cbr\u003eWith a width of 28.6mm, a Lug-to-lug of 35mm, and a thickness of 6.2mm, it suits wrists measuring approximately 15 to 18cm.
