OMEGA Speedmaster Chronoscope Co‑Axial Master Chronometer 43mm 329.30.43.51.03.001

The OMEGA Chronoscope collection has taken the legendary design of the OMEGA Speedmaster and combined it with the inspiration of OMEGA wrist chronographs from the 1940s.

This 43 mm model is crafted in stainless steel with a blue dial and silver-plated subdials.

Along with the blue anodised aluminium bezel ring with its tachymetric scale, the leaf-shaped hands and Arabic numerals are also rhodium-plated, with a unique "spiral" track design running beneath the numerals.

Most notably, the dial is printed with three distinctive timekeeping scales in a 1940s "snail" design, including a tachymeter scale, a pulsometer scale and a rangefinder scale.

Presented on a noble steel bracelet, the watch features a silver-plated small seconds at 9 o'clock and a silver-plated 60-minute and 12-hour recorder at 3 o'clock. The watch is powered by the OMEGA Co-Axial Master Chronometer calibre 9908 movement.
