Presented on a grey leather strap, this Speedmaster Racing Master Chronometer model features a 44.25 mm stainless steel case with an 18K Sedna™ gold bezel. The silicon nitride bezel ring includes the famous tachymeter scale in OMG Ceragold™.
On the matt grey dial, there is a distinctive racing style minute-track which gives the watch its name. There are also two subdials with rhodium plated 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 18K Sedna™ gold with white Super-LumiNova.
The watch is driven by the OMG Co-Axial Master Chronometer 9900, certified by METAS at the industry’s highest standard.
