Collectors prioritize this reference for its historical position as the first chronograph to feature a tachymeter scale on the external bezel rather than the dial. It is characterized by a 39mm symmetrical stainless steel case without crown guards, a matte black \"Base 1000\" metal bezel, and \"Broad Arrow\" handset. The watch is powered by the manual-wind Calibre 321 movement. Due to a short production window, surviving examples in original condition are rare. On the secondary market, prices typically range from the mid-six-figures to over $1,000,000 for exceptional specimens. A notable auction result occurred in 2021 when a 2915-1 sold for approximately $3.4 million, setting a record for the brand, though that specific example featured significant tropical dial oxidation."}, "listing_stats": {"count": 10, "median": 4450.0, "low": 3000.0, "high": 10100.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_7010129215563", "title": "OMEGA OMEGA Speedmaster
