Collectors value this reference for its specific technical modifications, including a brushed stainless steel case designed to eliminate glare and a radial sub-dial configuration intended for improved legibility. It houses the manual-wind Calibre 861 movement. Unlike standard commercial models, these watches were delivered directly to NASA and feature specific military-style engravings on the caseback, including the NASA serial number. Due to its extreme rarity and documented provenance in space exploration, the reference is highly sought after. On the secondary market, authentic examples typically command prices in the mid-to-high five-figure range, though exceptional specimens have exceeded $150,000 at auction. A notable production detail is that Omega later released a limited edition \"Speedmaster Tuesday\" tribute inspired by this specific radial dial design."}, "listing_stats": {"count": 7, "median": 11900.0, "low": 8000.0, "high": 20900.0, "brands": 1, "merchants": 4}, "listings": [{"id": "h_6789029265542", "title": "OMEGA Stainless steel OMEGA ref.
