At 38mm in stainless steel, the case is unusually large for its era — most watches of the early 1950s measured 33–35mm - which gives it a modern wrist presence that mid-century pieces rarely offer.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe black dial has been professionally restored and executed in the correct period style: cream Arabic numerals from 1 to 12, a white railroad minute track, lance hands, and a recessed subsidiary seconds register at 6 o'clock. The contrast of black, white, and cream gives the watch a clean, legible, almost military character. The inner case back carries the ACIER INOX marking and the case maker's stamp alongside the Longines winged hourglass.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eInside is the hand-wound Caliber 12.68Z, one of the great Longines workhorse movements, produced from 1938 onward. It runs at 18,000 vph with 17 jewels and around a 40-hour power reserve, and features the screwed chatons - each jewel set in its own threaded brass sleeve - that set Longines finishing apart from most of its contemporaries. The movement serial number 8491228 dates production to 1951. \u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e✓ Professional inspection by our watchmaker\u003cbr\u003e✓ One-year warranty\u003cbr\u003e✓ Express shipping included\u003cbr\u003e✓ Carefully packed and ready to wear\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCASE:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eStainless steel case\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eOversized diameter: 38mm\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eStraight lugs, classic round profile\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eSnap-on stainless steel case back, marked ACIER INOX\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDIAL:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eProfessionally restored gloss black dial\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eCream Arabic numerals 1–12\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eWhite railroad minute track\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eSubsidiary seconds at 6 o'clock with 30\/45\/60 scale\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eWhite lance-style hands\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eMOVEMENT:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eHand-wound Longines Caliber 12.68Z, 17 jewels\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eScrewed chatons - signature Longines finishing\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eSerial number 8491228, dating to 1951\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body break-words whitespace-normal\"\u003eSwiss made\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DuMarko","offers":[{"title":"Default Title","offer_id":50147779510524,"sku":null,"price":1890.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/2266\/1116\/files\/5H9A3958.jpg?v=1784201829","url":"https:\/\/dumarko.com\/products\/vintage-longines-swiss-watch-oversized-jumbo-case-cal-12-68z-black-dial-from-1951","provider":"DuMarko","version":"1.0","type":"link"}
