The robust stainless steel case boasts beefy lugs and shows no signs of polishing. While there are some normal signs of wear, such as superficial scratches, there are little to no marks of blows or pitting to the case. The watch retains its original small pushers and 32-tooth Omega-signed crown.

This particular timepiece houses the early Cal.321 movement with a 16 million serial number, indicating its production in 1958, just one year after the initial release of the Omega Speedmaster ref. 2915 in 1957. The movement remains remarkably clean, devoid of any signs of aging, pitting, or dirt. It runs flawlessly, keeping accurate time.

Rare find and seldom seen on the market, let alone in such remarkable condition.
