Omega Speedmaster Professional Moonwatch | Warm Tritium Patina I Ref. ST 145.022

The Omega Speedmaster Professional Ref. ST 145.022 is one of the most important vintage Moonwatch references, introduced in 1968 as the first Speedmaster Professional generation powered by Omega’s manually wound Calibre 861. It retains the classic 42mm stainless steel case, black tachymeter bezel, Hesalite crystal, and three-register chronograph layout that defines the traditional Speedmaster Professional.

The defining characteristic of this particular example is the warm cream-to-yellow patina visible across the tritium hour markers. The aged luminous material contrasts beautifully against the matte black dial, giving the watch an attractive and evenly aged vintage appearance

Condition

Please review the photographs carefully for an accurate representation. Scratches, bracelet wear, bezel wear, Hesalite crystal wear, dial aging, hand discoloration, or other signs of use consistent with age may be present. The tritium hour markers display attractive warm cream-to-yellow patina.
