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 24xxxxx, 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 likely been lightly polished, but 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 crystal is still present, signed with the Omega logo in the center. The original and correct “DON” (Dot Over Ninety) bezel is in excellent shape, with only minor wear.
Further, the watch comes fitted on its original flat-link Omega bracelet, coded 1506 and dating to the 4th quarter of 1966, with correct 516 endlinks. The bracelet is in great shape, considering these bracelets were easily broken or stretched, prompting Omega to replace them in the late 1960s, and it fits [approximately] a 6.5″ wrist.
