The very first Speedmaster stayed in production for two years until 1959 and was highly celebrated for being the first chronograph to ever bear a tachymeter scale on its bezel. During its two years of production, Omega introduced three consecutive sub-references, namely the 2915-1, -2 and -3, totalling less than 4,000 pieces only. While the two first iterations shared many attributes, the third generation announced the transition of the Speedmaster to the future reference 2998. The Speedmaster 2915-1 stands as today’s most coveted iteration for many reasons. First and foremost, its manufacturing era lasted slightly more than a year between 1957 and 1958, making this scarce reference genuinely difficult to find in today’s market. The 2915’s most attractive characteristic is its Huguenin Frères straight lug case, measuring 38.2mm in diameter and fitted with small 4mm pushers. It bears no crown guards and is adorned with a stainless-steel Base 1000 tachymeter bezel, with either a flat top three or a rounded 3 within the 130 mark. Furthermore, the broad arrow hands ensure perfect legibility against the black luminescent Singer dial. The reference was delivered either on the equally rare stainless steel 7077/6 bracelet with elastic links or fitted with a leather strap. The present Speedmaster 2915-1 is fitted with its original Seahorse double-bevelled case back, bearing the Speedmaster engraving to its outer rim. The early Omega dial script bears the coveted ‘oval O’ and is positioned right beneath /far below the applied logo. It is further elevated by its remarkable tropical dial, giving the present lot a unique appearance and appeal.
