Omega Speedmaster Broad Arrow

About this reference

The Omega Speedmaster reference 2915-1 was produced between 1957 and 1958 as the inaugural model of the Speedmaster line. 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.
