The recessed circular dial sits within the squared cushion case, creating a visual tension between the round silver dial and the geometric gold frame that is characteristic of Omega's refined 1960s dress designs. The black ostrich leather strap with its quill-pattern texture and gold-tone buckle completes a thoroughly period-correct presentation.\u003c\/div\u003e\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\u003cdiv\u003e\u003cstrong\u003eAbout Omega Caliber 620:\u003c\/strong\u003e\u003c\/div\u003e\u003cdiv\u003eThe Omega caliber 620 is a slim, hand-wound movement produced during the 1960s, valued for its reliability and precise timekeeping in dress watch applications where thinness and elegance were paramount design considerations. Omega's reputation during this era was at its height — the brand had already equipped NASA astronauts with the Speedmaster and was producing some of the finest dress watches in Switzerland simultaneously. The D6660 reference sits within Omega's gentleman's dress collection of the period, a watch built for refinement rather than sport, intended for the office, the dinner table, and occasions where gold and silver are the appropriate language. Collectors of vintage Omega increasingly prize these cushion-case manual wind references for their pure 1960s character, precious metal construction, and the irreplaceable Florentine finishing technique that is rarely seen in modern watchmaking. For the discerning buyer, this watch represents a wearable piece of Swiss horological history in solid gold.\u003c\/div\u003e","brand":"Omega","offers":[{"title":"Default Title","offer_id":47596191088830,"sku":"POTC2627W","price":2225.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0508\/5724\/6910\/files\/Vintage-Omega-D6660-27mm-18K-Gold-Cushion-Manual-Watch-Watch-Watch.jpg?v=1780417171","url":"https:\/\/it.assayjewelers.com\/products\/vintage-omega-d6660-27mm-18k-gold-cushion-manual-watch-watch","provider":"ASSAY","version":"1.0","type":"link"}
