Pre-owned Omega Speedmaster Chronoscope ref 329.30.43.51.02.001 (2023) is one of the most interesting modern interpretations of the Speedy because it looks beyond the collection’s spacefaring legacy and instead draws inspiration from Omega’s chronograph wristwatches of the 1940s. The Chronoscope takes its name from its ability to display multiple timing functions at once, and nowhere is that more evident than on the beautifully detailed dial. In addition to the chronograph, the watch features three historic timing scales arranged in a distinctive spiral “snail” pattern: a tachymeter for measuring speed, a pulsometer for calculating heart rate, and a telemeter for determining the distance of an event based on the time between seeing it and hearing it. While these scales originated as practical tools decades ago, today they give the Chronoscope a unique vintage character that sets it apart from other Speedmasters. The example you see here pairs a silvery dial with blued Arabic numerals, leaf-shaped hands, and a matching blue tachymeter bezel. Shop OMEGA Speedmaster Collection
