OMEGA Speedmaster Super Racing

Omega's Speedmaster Super Racing, reference 329.30.44.51.01.003, is a chronograph in a 44.25 mm steel case. Thickness runs to 14.9 mm with a lug-to-lug of 50 mm, giving it real presence on the wrist. The black dial sits under a sapphire crystal treated with anti-reflective coating on both sides. Inside is the self-winding calibre 9920, a Master Chronometer movement with column wheel and Co-Axial escapement, certified to resist magnetic fields up to 15,000 gauss. Two barrels mounted in series give it a 60 hour power reserve, and it adds a tachymeter scale alongside the chronograph and small seconds functions. A sapphire display back shows the finish. The steel bracelet closes with a foldover butterfly clasp, rated to 50 metres.
