Steel on leather strap
This Speedmaster Racing Master Chronometer model features a 44.25 mm stainless steel case with a black ceramic bezel ring that includes the famous tachymeter scale in orange wording and Liquidmetal® numbers. The black leather strap is micro-perforated revealing an orange rubber interior.
On the matt black 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 hands are a mix of varnished orange and white, while the arrowhead indexes are 18K white gold with white Super-LumiNova.
The watch is driven by the OMEGA Co-Axial Master Chronometer 9900, certified by METAS at the industry’s highest standard.
