OMEGA Speedmaster Moonwatch Professional

Omega's Speedmaster Moonwatch Professional "Reverse Panda," reference 310.30.42.50.01.004, has a 42 mm steel case. It measures 13.54 mm thick with a lug-to-lug of 47.5 mm, and the black dial sits against a reverse panda layout typical of this reference. A manual-winding chronograph calibre 3861 drives the watch, fitted with a Co-Axial escapement and certified as a Master Chronometer to METAS standards, resisting magnetic fields up to 15,000 gauss. Power reserve runs to 50 hours. The sapphire crystal carries anti-reflective treatment on its inner surface. As a chronograph, it combines a tachymeter scale with small seconds, and a sapphire display back shows the movement. The steel bracelet closes with a foldover clasp fitted with a comfort setting. Water resistance holds at 50 metres.
