This Omega Speedmaster Professional Ref. 1450022 / 3450022 represents one of the final evolutions of the classic Moonwatch with tritium lume. Featuring the iconic 42mm asymmetrical stainless steel case, it houses the legendary manual-winding Caliber 861, known for its robustness and reliability. This version is distinguished by its “T SWISS MADE T” tritium dial, marking it as one of the last Speedmasters before the switch to Super-LumiNova. The original 1479 bracelet with 812 end links adds period-correct authenticity and comfortable wear. With its Hesalite crystal, black stepped dial, and tachymeter bezel, this watch embodies the essential DNA of the Speedmaster legacy. A true collector's piece, it offers vintage charm with reliable performance, bridging the gap between early Moonwatch heritage and modern production.
