Collectors value these references for their rarity and technical divergence from standard Moonwatch specifications, often featuring the Calibre 861 or 1040 movements. These prototypes frequently showcase unique dial configurations, such as the \"Alaska Project\" radial sub-dials or experimental white matte finishes designed for thermal reflection. Case constructions vary from standard asymmetrical designs to reinforced housings intended for extreme environments. Due to their scarcity and historical significance in NASA testing, these watches rarely appear on the secondary market, typically commanding prices in the mid-to-high six-figure range. A notable auction result occurred in 2021 when a 1972 Speedmaster Professional Alaska II prototype sold for over $500,000, underscoring the high demand for documented developmental pieces with verified provenance."}, "listing_stats": {"count": 753, "median": 5100.0, "low": 3000.0, "high": 74000.0, "brands": 1, "merchants": 7}, "listings": [{"id": "h_16484156408153", "title": "OMEGA Omega
