The Chronoscope collection has taken the legendary Speedmaster design and combined it with inspiration from OMEGA's 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 1940's ''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. 5 bar (50 metres / 167 feet)
