Lot Essay

According to the Archives of Montres Omega, the present watch was sold to Germany on 21 October 1963.

This watch is from the second series of the Speedmaster Professional line launched in 1959; the initial reference CSK 2998 became ST 105.002 in 1962. The model differs from the first series by the Alpha hands, the tachymetre scale now in black aluminium and calibrated to 500-60 km/h instead of the previous "Base 1000 300-60 km/h".
