Omega Speedmaster Professional Moonwatch Ref. 3570.50.00

The Omega Speedmaster Professional Moonwatch Ref. 3570.50.00 is one of the most iconic mechanical chronographs ever produced — a direct descendant of the watches worn by NASA astronauts on all six lunar missions.

This 2009 example features a 42mm stainless steel case, the classic Hesalite crystal, and the manual-wind Omega Caliber 1861 movement. The matte black dial, three-register chronograph layout, and aluminum tachymeter bezel remain faithful to the original Moonwatch design.

It comes as a full set with box and papers, and includes both:

• The original Omega stainless steel bracelet, and

• A black Omega nylon strap with OEM Omega deployment clasp — adding modern comfort to this heritage-driven timepiece.

The watch is in 8.5/10 condition, showing light signs of wear consistent with careful use.
