The brushed steel of the case interacts with a gold-plated bezel, whose corners feature fine engraved striations. The bracelet, integrated into the case, reprises this two-tone style: steel links punctuated with golden elements, without any visual break between the watch and the wrist.\u003c\/p\u003e\n\u003cp\u003eThe silvered dial features a vertical satin finish that catches the light in regular bands. No numerals, no baton markers on the dial itself: four applied dots mark the four cardinal points, echoed by golden markers set on the rehaut. The golden lance-shaped hands are accompanied by a fine seconds hand. The \u003cem\u003eChronos\u003c\/em\u003e signature appears in cursive script at six o’clock, beneath the Seiko logo.\u003c\/p\u003e\n\u003cp\u003eBeneath this dial lies the element that distinguishes this piece: the Seiko 9531 caliber, a movement from the brand’s family of high-precision quartz movements. It equipped the upper ranges of the catalog — Dolce, Chronos and Laurel — and directly precedes the caliber used in the first Grand Seiko quartz. The performance highlighted at the time was that announced by Seiko when it was marketed; on a forty-year-old piece, actual rate performance depends on the aging of the movement and its maintenance.\u003c\/p\u003e\n\u003cp\u003eThe Chronos line was developed for the Japanese domestic market in the early 1980s and was distributed for only a short decade. These pieces were never marketed in Europe through official channels, which explains their relative rarity outside Japan. At 6.6mm thick and 33mm Lug-to-lug, this one slips under a cuff effortlessly.\u003c\/p\u003e\n\u003ch3\u003eThree points to note\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-precision 9531 caliber\u003c\/strong\u003e — a movement reserved for the upper ranges of Seiko, inherited from the work carried out on Grand Seiko quartz.

The performance highlighted at its release was markedly above that of a standard quartz from the same period. These are the original announced specifications: on a vintage piece, the observed timekeeping depends on the age of the movement and its maintenance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat year does this piece date from?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt was produced in 1985, placing it at the heart of the Chronos period.

Its compact format and slimness place it in the dress watch category, equally wearable by a man or a woman.

The two-tone bracelet is the one delivered with the watch, integrated into the case — it is not an interchangeable bracelet with standard lugs. The Lug width measures 17mm.
