The Speedmaster CK2915-1 sold for CHF 3,115,500 far exceeding the estimated auction price of 80,000 to 120,000 Swiss Francs.

While many collectables are valued for their absence of use, this extraordinary Omega has lived an active life, resulting in a unique "tropical" dial that has aged to a vibrant milk-chocolate shade.

As well as being rich and vivid, the brown tone is incredibly even throughout. Moreover, the luminous material on both the dial and hands have aged at the same pace, giving the display an attractive golden tone.

Omega watches with the reference CK2915, were only made between 1957 and 1959 and produced in just three different iterations, making the CK2915-1 one of the very first and most collectible Speedmaster models. These editions are considered “the grail” by passionate collectors, as they’re among the first batch of Speedmaster watches to draw power from Omega’s mighty Calibre 321.

“Key differences to later generation models include the “Broad Arrow3 minute and hour hands and the oval “O” of Omega”
