Omega Speedmaster Moonwatch Professional decades have passed, yet the Speedmaster remains instantly recognizable, as reference 310.30.42.50.01.001 demonstrates. Omega preserved the exact functional layout that conquered space travel, keeping the matte step dial, sloped minute track, and classic Hesalite front. The real upgrade sits inside, with the hand-wound Calibre 3861, taking the historical 1861 movement design and adding a silicon balance spring alongside METAS certification. The brushed five-arched-links-per-row bracelet completes the watch, a fitting reminder that some designs endure because they keep evolving without losing their identity.

Offered pre-owned, this Omega Speedmaster Moonwatch Professional Steel Watch 310.30.42.50.01.001 comes with its manufacturer’s box and official paperwork.
