Speedmaster Chronoscope

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.
