This Speedmaster known as the ‘CB Case’ is rare because nearly all Cal. 321 Speedmaster cases were manufactured by the Omega case-maker, Huguenin Freres & Co, in Le Locle, Switzerland and thus signed "HF" inside the case-back. Only in 1966 with the reference 105.012 did Omega use an additional case-maker, and signed "CB" in the case-back. These cases were only manufactured during a very short period of time and are extremely rare. This case has a particularity known as ‘flat lugs’. The lyre lugs on these cases had a flat edge at the top, making them easily recognizable compared to other lyre lug cases.
In addition, this Speedmaster has its original Pulsometer bezel, which was optional in the 1960’s on this model. This is an original Pulsometer bezel, which is different from the modern one. It has the inner circle line and graduations versus the modern one that does not have either.
The rare CB case paired with the pulsations bezel makes this an almost unique watch.
