OMEGA Speedmaster Moonwatch Professional

The Omega Speedmaster Moonwatch Professional 310.32.42.50.01.001 is a chronograph with a 42 mm steel case. The case measures 13.18 mm thick with a 47.5 mm lug-to-lug span, and the dial sits under a Hesalite crystal marked with the Omega logo at its centre. Inside is the manual-winding calibre 3861, a Co-Axial escapement movement certified as a Master Chronometer by METAS and resistant to magnetic fields up to 15,000 gauss. It runs on a free-sprung balance with a silicon balance spring and offers 50 hours of power reserve. The black dial carries a tachymeter scale and small seconds, standard functions for this chronograph. A black coated nylon fabric strap with reinforced fabric surface closes with a steel foldover clasp. Water resistance stands at 50 metres.
