This Speedmaster Racing Master Chronometer model features a 44.25 mm 18K Sedna™ gold case on a blue leather strap. The bezel includes a blue ceramic ring and the famous tachymeter scale in OMEGA Ceragold™.
On the sun brushed blue dial, there is a distinctive racing style minute-track which gives the watch its name. There are also two blued subdials 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 OMEGA Co-Axial Master Chronometer 9901, certified by METAS at the industry’s highest standard.
The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
The chronograph function is a mechanism for measuring time intervals. A can therefore be used to time events while displaying the time like any traditional watch.
