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 OMEGA’s exclusive Bronze Gold, with an oxidised bronze dial featuring a special patina and opaline finish. Along with a polished brown ceramic bezel ring with its tachymeter scale in \"vintage\" enamel, the leaf-shaped hands and Arabic numerals also feature an 18K Bronze Gold PVD coating. A unique “spiral” track pattern runs 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 brown leather strap, 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 manual-winding OMEGA Co-Axial Master Chronometer Calibre 9908.
