A beautiful neo-vintage Speedmaster Professional Ref. 3590.50 from 1993, representing the final era of tritium-lumed Moonwatches before the transition to Super-LumiNova. This example stands out with a highly attractive tropical “stardust” dial, where the black surface shows subtle grain and warmth under light, paired with even pumpkin-colored tritium lume on the hour markers and hands. The result is a rich, honest patina that collectors actively seek.

The classic 42 mm twisted-lug steel case retains strong lines with light, age-appropriate wear, complemented by the original black tachymeter bezel. Inside beats the legendary Omega Caliber 861, a hand-wound, cam-lever chronograph known for its robustness and historical significance as a NASA-qualified movement.

Offered as a Full Set, this Speedmaster includes its original Omega box, warranty papers/cards, manuals, and accessories, making it especially desirable to collectors. A true Moonwatch with character, provenance, and timeless design—ready to be worn or cherished as a long-term vintage piece.

Based in Melbourne.

Thanks again everyone! 😁
