Omega Speedmaster Professional Moonwatch "Sapphire Sandwich" — Ref. 311.33.42.30

A modern Moonwatch that pays homage to Omega's own history — the "Sapphire Sandwich" nickname comes from the double sapphire crystal construction front and back, letting you view the manually-wound caliber 1861 movement in full while keeping the iconic hesalite-style profile Omega is known for on the dial side.

This 2020 example is in excellent condition with only light wear — case lines are crisp, the tachymeter bezel is clean, and the movement runs true. Full set included: original box and papers.

The Speedmaster Professional needs no introduction. Flight-qualified by NASA, worn on every crewed lunar mission since Apollo 11, and still hand-assembled in Bienne the same way it was in 1969. This isn't a watch chasing history — it's the watch that made it.
