About the Omega Speedmaster Chronoscope

Omega introduced the Speedmaster Chronoscope in 2021. Its dial borrows the layered scale layout of 1940s chronographs, combining a tachymeter, a telemeter for measuring distance by sound and a pulsometer for counting heartbeats. The 43 mm case is slightly larger than the Speedmaster Professional. Power comes from manual winding Co-Axial Master Chronometer chronograph calibres, the 9908 and 9909. Omega's current catalogue lists the Chronoscope in stainless steel, Bronze Gold and Moonshine Gold, on steel or gold bracelets and leather straps.
