The Omega Speedmaster Racing 329.32.44.51.01.001 is a chronograph with a 44.25 mm steel case. It measures 14.92 mm thick and spans 50 mm lug to lug, with a domed sapphire crystal treated with antireflective coating on both sides. Inside is the self-winding calibre 9900, a column-wheel chronograph movement with a Co-Axial escapement and a silicon balance-spring, certified as a Master Chronometer by METAS and resistant to magnetic fields up to 15,000 gauss. It runs on two barrels mounted in series for a 60-hour power reserve and includes a time zone function alongside the small seconds and tachymeter. The black dial is paired with a black calf leather strap on a steel foldover clasp. A sapphire display back shows the movement. The case holds a 50 metre water resistance rating.
