Omega Speedmaster Professional Moonwatch Sapphire

Few watches carry a legacy as profound as the Omega Speedmaster Professional — the only watch ever qualified by NASA for all manned space missions, and the first watch worn on the Moon. This sapphire crystal variant houses the legendary manual-winding Calibre 1863, visible through a transparent exhibition caseback, giving collectors a rare window into horological history. Timeless, historically significant, and endlessly collectible.
