The Chronoscope collection has taken the legendary Speedmaster design and combined it with inspiration from OMEGAs chronograph wristwatches from the 1940s.This 43 mm model is crafted in stainless steel with a blue dial with silvery subdials. Along with a blue anodized aluminium bezel ring with its tachymeter scale, the leaf-shaped hands and Arabic numerals are rhodium-plated, with a unique spiral track pattern running beneath the numbers.Most notably, the dial is printed with three distinctive timing scales in a 1940s snail design, including a tachymeter scale, a pulsometer scale and a telemeter scale.Presented on a stainless steel bracelet, the watch features a silvery small-seconds counter at 9H, and a silvery 60-minute and 12-hour recorder at 3H. Inside, the timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 9908.
