This is a mint example of the Omega Speedmaster “Moonwatch”, the same reference that was used for space flight to the moon. This example was produced in 1976, as the caseback suggests (145.022-76).
This Omega Speedmaster is in excellent condition. The case does not show signs of overpolishing, and the beveled edges are still present in the lugs. The dial is mint, with no blemishes, chips, etc. The original lume is all present in the dial, with only minor chipping in the minute hand. The lume has aged to a beautiful cream patina. The original bezel is in excellent condition, with only a few minor chips in the paint.
