Omega Speedmaster Professional 1963-69

Speedmaster ST 105.003 with the new baton hands but still with straight lugs -1963

With reference ST 105.002 in 1962 and reference ST 105.003 in 1963, Omega introduced the Speedmaster's typical straight baton hands.

That same year - with reference ST 105.012 - a 42 mm asymmetrical case, adding protection to the chronograph pushers and crown, was released. This is the case that remains, little changed, in production today. The Professional marking appeared below the Speedmaster logo on dial during summer 1965.
