The original Omega Speedmaster from 1957The first ever Omega Speedmaster was introduced in 1957 with the reference CK2915. One of the most distinct sport watches to ever be created, it was the first to feature the tachymeter on the bezel, a clever solution that was eventually copied by the rest of the industry, including the Rolex Daytona that was launched in 1963. The CK2915 already had the unmistakable features of the classic Omega chronograph as we know it today: the tachymeter scale printed on the bezel, the recessed sub dials in the 3-6-9 position, the signature below 12 o’clock and the screw-down caseback. It also notably featured “broad arrow” hands and short, straight lugs — features that we see sporadically in the history of the Speedmaster. |
