A chronometer is not a chronograph: it is a movement subjected to an official precision test, over several days, in several positions and at several temperatures, before being cased. Omega reserved this designation for the Constellation, heir to the precision records the manufacture had been accumulating in observatory trials since the 1930s. This is why the dial bears, in full, \u003cem\u003eChronometer\u003c\/em\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the Omega 712 calibre?\u003c\/strong\u003e\u003cbr\u003eAn automatic movement produced from 1967 to 1976, with twenty-four jewels, beating at 19,800 vibrations per hour, with a 42-hour power reserve. Its distinction lies in one figure: \u003cstrong\u003e3.00mm in height\u003c\/strong\u003e, making it the thinnest automatic calibre ever produced by Omega. It is this movement that allows this Constellation to measure 7.3mm, Crystal included — a dimension no automatic of the period could match.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the dial original?\u003c\/strong\u003e\u003cbr\u003eYes. The brushing is even right to the edge, the applied markers are made in a single piece, and the four printed lines — Constellation, Omega, Chronometer, Automatic — are sharp and correctly spaced, which a redial rarely achieves all at once. This dial has not been retouched.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it need to be worn every day to keep running?\u003c\/strong\u003e\u003cbr\u003eIt is an automatic movement: it winds through wrist motion and retains 42 hours of running time once wound. Worn regularly, it requires nothing. Left at rest for two days, it stops and starts again with a few gentle turns of the wrist or about ten turns of the crown. It has neither date nor window to reset: only the time needs to be set again.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this piece suitable for a slim or a larger wrist?\u003c\/strong\u003e\u003cbr\u003eWith a diameter of 34.5mm, 38.5mm Lug-to-lug, and a thickness of 7.3mm, it suits wrists of around 15 to 18.5cm — a guide, never a rule: everyone wears what they like. Its thinness matters here as much as its diameter: at 7.3mm, it slips under a cuff without catching and appears more discreet than a round watch of the same size twice as thick. The 18mm Lug width is one of the most common, which leaves a full choice of replacement straps.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e ","brand":"Omega","offers":[{"title":"Default Title","offer_id":54818953363793,"sku":"cal.712 serial:26520219 ref:157.0001","price":1732.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/montre-omega-constellation-157-0001-acier-extra-plate-1967-atelier-victor-1.jpg?v=1789505017","url":"https:\/\/ateliervictor.co\/en\/products\/omega-constellation-watch-157-0001-steel-ultra-thin-1968","provider":"Atelier Victor","version":"1.0","type":"link"}
