Omega Speedmaster Professional Moonwatch | Orange Patina | Black Dial | Hesalite

The Omega Speedmaster Professional Moonwatch Ref. 3570.50 is one of the most recognizable and enduring modern interpretations of Omega’s legendary manual-wind chronograph. This reference features the traditional 42mm stainless steel Moonwatch case, matte black dial, black tachymeter bezel, Hesalite crystal, solid stainless steel caseback, and stainless steel bracelet. It is powered by Omega’s manually wound Calibre 1861, offering the classic mechanical experience associated with the Speedmaster Professional.

The beauty of this particular example is the warm orange-toned patina visible on the luminous hour markers around the dial.This distinctive aging gives the watch additional neo-vintage character and creates an attractive contrast against the matte black dial and white chronograph markings.
