Omega Speemaster Racing Chronometer Ref. 329.30.44.51.06.001

Omega Speemaster Racing Chronometer

This Speedmaster Racing Master Chronometer model features a 44.25 mm stainless steel case and bracelet with a black ceramic bezel ring that includes the famous tachymeter scale in orange wording and Liquidmetal™ numbers.

On the sun brushed 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 hands are either blackened or varnished orange, while the arrowhead indexes are blackened 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.
