It combines the iconic asymmetrical Professional case with the movement that established the Speedmaster's reputation for precision, durability and reliability under the most demanding conditions.\u003c\/p\u003e\n\u003cp data-start=\"702\" data-end=\"1137\"\u003eThis example is an exceptionally honest survivor and a watch that ticks many of the boxes seasoned collectors search for. The original stepped dial remains beautifully preserved, accompanied by its highly sought-after DON (Dot Over Ninety) bezel. Reference checks against the Omega Speedmaster reference literature confirm the originality of the watch's key components, resulting in a remarkably correct and highly collectible example.\u003c\/p\u003e\n\u003cp data-start=\"1139\" data-end=\"1500\"\u003eAt its heart beats the legendary Omega calibre 321, the column-wheel chronograph movement that powered the Speedmasters worn during NASA's Gemini and Apollo programmes. This example is further distinguished by its rare OXG-marked balance, identifying it as an export-market watch and adding another layer of collectibility for dedicated Speedmaster enthusiasts.\u003c\/p\u003e\n\u003cp data-start=\"1502\" data-end=\"1691\"\u003eAdding further desirability, the watch retains its original 1116 bracelet with sought-after 30-marked end links, a detail often missing from examples that have spent decades in circulation.\u003c\/p\u003e\n\u003cp data-start=\"1693\" data-end=\"1982\"\u003eRecently serviced and supplied with a 2-year warranty, the watch is ready to be enjoyed while remaining a significant collector-grade example. The chronograph functions correctly, with a slight drag visible at the six o'clock hour recorder—a characteristic noted for complete transparency.\u003c\/p\u003e\n\u003ch3 data-section-id=\"fcq80n\" data-start=\"1984\" data-end=\"2005\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cul data-start=\"2007\" data-end=\"2636\"\u003e\n\u003cli data-section-id=\"1bw80eg\" data-start=\"2007\" data-end=\"2021\"\u003eBrand: Omega\u003c\/li\u003e\n\u003cli data-section-id=\"19rbpc4\" data-start=\"2022\" data-end=\"2064\"\u003eModel: Speedmaster Professional Pre-Moon\u003c\/li\u003e\n\u003cli data-section-id=\"vn2hec\" data-start=\"2065\" data-end=\"2085\"\u003eReference: 145.012\u003c\/li\u003e\n\u003cli data-section-id=\"1u2nthp\" data-start=\"2086\" data-end=\"2115\"\u003eProduction Year: Circa 1967\u003c\/li\u003e\n\u003cli data-section-id=\"4pksj3\" data-start=\"2116\" data-end=\"2182\"\u003eMovement: Omega Calibre 321 Manual-Wind Column Wheel Chronograph\u003c\/li\u003e\n\u003cli data-section-id=\"rtmi4v\" data-start=\"2183\" data-end=\"2218\"\u003eDial: Original Black Stepped Dial\u003c\/li\u003e\n\u003cli data-section-id=\"172hu6r\" data-start=\"2219\" data-end=\"2275\"\u003eBezel: Original DON (Dot Over Ninety) Tachymeter Bezel\u003c\/li\u003e\n\u003cli data-section-id=\"5uivit\" data-start=\"2276\" data-end=\"2330\"\u003eCase: Stainless Steel Asymmetrical Professional Case\u003c\/li\u003e\n\u003cli data-section-id=\"dywrgt\" data-start=\"2331\" data-end=\"2371\"\u003eBracelet: Original Omega 1116 Bracelet\u003c\/li\u003e\n\u003cli data-section-id=\"1whrraf\" data-start=\"2372\" data-end=\"2410\"\u003eEnd Links: Original No. 30 End Links\u003c\/li\u003e\n\u003cli data-section-id=\"15ztd6j\" data-start=\"2411\" data-end=\"2430\"\u003eCrystal: Hesalite\u003c\/li\u003e\n\u003cli data-section-id=\"ydgxol\" data-start=\"2431\" data-end=\"2448\"\u003eCase Size: 42mm\u003c\/li\u003e\n\u003cli data-section-id=\"h0cz7q\" data-start=\"2449\" data-end=\"2504\"\u003eFunctions: Chronograph, Hours, Minutes, Small Seconds\u003c\/li\u003e\n\u003cli data-section-id=\"bc4557\" data-start=\"2505\" data-end=\"2555\"\u003eSpecial Features: Rare OXG Export-Market Balance\u003c\/li\u003e\n\u003cli data-section-id=\"17iyc4\" data-start=\"2556\" data-end=\"2608\"\u003eCondition: Fully Serviced, Highly Original Example\u003c\/li\u003e\n\u003cli data-section-id=\"34uwma\" data-start=\"2609\" data-end=\"2636\"\u003eWarranty: 2-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-start=\"2638\" data-end=\"2877\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eA highly original Pre-Moon Speedmaster combining a calibre 321 movement, DON bezel, OXG-marked balance and original 1116\/30 bracelet—precisely the details that separate a good vintage Speedmaster from a truly exceptional collector's piece.\u003c\/p\u003e","brand":"Perpetual Watch Lover (PWL)","offers":[{"title":"Default Title","offer_id":54547503481161,"sku":null,"price":9750.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0238\/6352\/5456\/files\/DSF0652.jpg?v=1780649333","url":"https:\/\/perpetualwatchlover.com\/products\/omega-145-012-pre-moon-cal-321-don-bezel","provider":"Perpetual Watch Lover (PWL)","version":"1.0","type":"link"}
