OMEGA Speedmaster Moonwatch Professional

The Omega Speedmaster Moonwatch Professional 310.60.42.50.99.002 is a chronograph in a 42 mm Moonshine gold case. Thickness runs to 13.18 mm with a lug-to-lug of 47.46 mm, giving the case a compact, wearable footprint. Inside is the manual-winding calibre 3861, a Co-Axial chronograph movement certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss. A sapphire crystal with anti-reflective treatment protects the yellow dial, itself finished in the same Moonshine gold tone. The chronograph pairs with a tachymeter scale and small seconds, and the caseback is transparent to show the movement. Power reserve stands at 50 hours. The Moonshine gold bracelet closes with a foldover clasp, and Omega rates the whole case to 50 metres.
