The Chronoscope collection merges the Speedmaster design with 1940s OMEGA chronograph inspiration. This 43mm stainless steel model features a silvery dial, a blue anodized aluminum bezel with a tachymeter scale, and blued leaf-shaped hands and Arabic numerals. The dial includes three 1940s-style timing scales: tachymeter, pulsometer, and telemeter. It comes with a blue leather strap, a small-seconds counter at 9H, and a 60-minute and 12-hour recorder at 3H. Powered by the OMEGA Co-Axial Master Chronometer Calibre 9908.
