Omega Speedmaster Professional Moonwatch | 42mm Black Dial | Ref 3570.50 I

The Omega Speedmaster Professional Moonwatch Ref. 3570.50 is one of the most iconic modern Speedmaster references, staying true to the classic Moonwatch formula with a 42mm stainless steel case, black tachymeter bezel, Hesalite crystal, and manual-wind chronograph movement. It delivers the traditional Speedmaster look collectors love, with the same timeless layout that has made the Moonwatch one of the most recognizable chronographs ever made.

This example stands out thanks to the warm patina visible on the dial markers, giving the watch extra vintage character and a more unique wrist presence. The aged tones add depth against the black dial, making this piece feel more special than a standard clean-marker 3570.50 while still keeping the classic Moonwatch identity intact.
