Up for grabs is an excellent example of an Omega Speedmaster, of the so-called “Pre-Moon” models, Reference 105.012-66, circa 1966, with a correct serial range of 25xxxxx, with a rare “CB” case. CB stands for the casemaker, Le Centrale Boites, which produced Speedmaster cases for Omega for a short 6 months in 1966, and only for this specific reference.
This example is in beautiful vintage condition. The case has never been polished, and the lugs are still very thick and even, with original bevels present in the lugs; there are no tool marks on the caseback. The dial is perfect, with no blemishes. The original tritium lume is still present in both hands and dial, aged to a striking golden yellow color. The original and correct “DON” (Dot Over Ninety) bezel is in excellent shape, with only minimal wear.
