This Speedmaster Racing model features a 44.25 mm stainless steel case and bracelet with a black ceramic bezel ring adorned with a white enamel-filled tachymeter scale.
A notable feature of the white dial is the racing-style minute-track that gives the watch its name. Contrasting the white, there are two blackened subdials with applied rings, and a 6 o'clock date window in a similar hue. The hands and arrowhead indexes are blackened with white Super-LumiNova, while orange accents appear on the "Speedmaster" logo and the tip of the central seconds hand.
Powering the timepiece is the OMEGA Co-Axial Master Chronometer 9900, verified to the peak industry standard by METAS.
