This Speedmaster Racing Master Chronometer model features a 44.25 mm stainless steel case on a black leather strap and a black ceramic bezel ring that includes the famous tachymeter scale filled with white enamel. On the white dial, there is a distinctive racing style minute-track which gives the watch its name. There are also two subdials with blackened applied rings as well as a 6 o’clock date window that blends with the colour of the dial. The hour and minute hands and arrowhead indexes are blackened with white Super-LumiNova. Orange touches include the "Speedmaster" name and the tip of the central seconds hand. The watch is driven by the OMEGA Co-Axial Master Chronometer 9900, certified by METAS at theindustry's highest standard.
