The present timepiece is extremely rare thanks to its three notable particularities. Firstly, the dial of the watch has aged delicately into a gorgeous and awe-inspiring tone of chocolate brown, bestowing a unique sense of individuality onto the watch. Secondly, the present example belongs to the last batch of the reference 145022-69 ST in which the caseback makes no reference to the moon landing. The present watch has the Hippocampus engraved on the case back which was later replaced by the engraved inscription "first watch worn on the moon" - known by collectors as “straight writing”. Thirdly, the present reference is also notable for being the first model fitted with the new dial type with painted OMEGA symbol in place of the former applied symbol.
