Collectors distinguish this reference as the \"Holy Grail\" because it is the only vintage Speedmaster to house the automatic Calibre 1045, a movement based on the Lemania 5100. The watch features a 42mm stainless steel case that is thicker than the standard Moonwatch to accommodate the central minute chronograph hand and day-date complications. It typically features a \"Moonwatch\" style dial with a tachymeter scale integrated under the mineral crystal. On the secondary market, prices generally range from $20,000 to $35,000 depending on the presence of the original 1450 bracelet and 808 end links. A notable production detail is that many examples were serviced with later functional replacement parts, making original \"non-service\" dials and hands significantly more valuable to collectors."}, "listing_stats": {"count": 453, "median": 6250.0, "low": 3000.0, "high": 74000.0, "brands": 1, "merchants": 7}, "listings": [{"id": "h_8029446734146", "title": "OMEGA Speedmaster Moonwatch Omega Co-Axial Master Chronometer Moonphase Chronograph -
