The Omega Speedmaster Professional Moonwatch needs no introduction — it is the watch that went to the moon and never came back down to earth in terms of prestige. This 2023 example references 310.30.42.50.01.001 features the classic black stepped dial, the hesalite crystal, and the manually-wound calibre 1861 movement. Presented in very good condition with original box, this is an icon at an accessible price point.
