Launched in 1957 as a sport and racing chronograph, the Speedmaster model has become one of the most well-known chronograph models ever. The first Speedmaster model was the reference 2915, featuring a distinctive luminous broad-arrow shaped hour hand. It was outfitted with the caliber 321, which would be used until 1968, when it was replaced by the caliber 861.
The present watch is a mint example of a rare Speedmaster Professional reference 105.012-66 with a La Centrale Boîte case, a Speedmaster case suppliers to Omega only for one year in 1966. Featuring a flat top with an angular bevel on the lugs, the CB with its subtle originality is a must-have for most Speedmaster aficionados .
This particular watch has a very impressive dial and bezel which have turned a light shade of grey hence the nickname "Ghost Grey". The light shade of grey compliments the loss of luminous markers. This combo grey of dial and bezel, the CB case and the crisp case back logo engraving add to the desirability of this example, and will be enjoyed by a collector for years to come.
