OMEGA Speedmaster Moonwatch Professional

Omega Speedmaster Moonwatch Professional 310.60.42.50.02.001 has a 42 mm case in white gold, part of Omega's Canopus Gold line. The case measures 13.18 mm thick with a lug-to-lug span of 47.5 mm, and the silver dial sits under a domed sapphire crystal with antireflective treatment inside. Inside is the manual-winding calibre 3861, a Co-Axial chronograph movement certified as a Master Chronometer by METAS and resistant to magnetic fields up to 15,000 gauss. Power reserve runs to 50 hours. As a chronograph, it combines small seconds with a tachymeter scale on the dial, and a display back shows the movement. The white gold bracelet closes with a foldover clasp fitted with a comfort setting. Water resistance reaches 50 metres, backed by that same secure clasp.
