Vintage Omega Speedmaster Professional Moonwatch Tritium 145.022 - 42mm - 1985

This vintage 1985 Omega Speedmaster Professional Moonwatch is powered by the caliber 861 manual-wind movement, serviced in October 2025. It retains its original tritium dial with beautifully patina’d hour markers. The dial shows no wear, and the black lacquer in the caseback engraving remains fully intact.

The bezel is well-preserved, showing only very light wear that is barely visible. Both the case and original Omega Speedmaster bracelet reference 1171 are in excellent condition, with only minor surface scratches. The bracelet is long enough to fit wrists up to 21,5cm, making it suitable even for very large wrists.

Overall, this Moonwatch presents in incredible condition with its original polish and stands as a highly collectible yet wearable piece.
