Omega have confirmed that this "Medical Speedy" was originally supplied to the NAAFI in 1966 for sale to military personnel. The original Pulsation bezel was one of 4 optional bezels available as a special order from Omega, and this one is the correct 60's version with the line running round the centre. The dial of this important 'Ed White' is in truly exceptional condition and has aged beautifully over the years, the long slender Tritium indexes have taken on a lovely warm yellow colour that is matched by the Tritium hands with later chronograph recorder.
