The Omega Speedmaster Professional Moonwatch Ref. 3570.50.00 is one of the most iconic chronographs ever produced, celebrated for its direct connection to the history of space exploration and its timeless design. Known as the “Moonwatch,” this legendary timepiece carries the heritage of the model worn by astronauts during the Apollo 11 Moon Landing.
This example features the classic 42mm stainless steel case paired with the iconic black dial, luminous hour markers, and the instantly recognizable tachymeter bezel. Inside is Omega’s reliable manual-wind Caliber 1861 movement, the direct descendant of the movement used in NASA-qualified Speedmasters. The hesalite crystal and solid caseback maintain the authentic Moonwatch configuration that collectors love.
The watch is presented as a complete set including the original box, papers, and an eBay Authentication Card, giving buyers confidence in both authenticity and provenance.
A true staple for collectors and enthusiasts alike, the Speedmaster Professional remains one of the most recognizable and historically significant watches ever made.
Whether you’re adding to a collection or purchasing your first serious chronograph, the Omega Speedmaster Moonwatch is a piece that never goes out of style.
