OMEGA Speedmaster Chronoscope (Paris 2024)

Omega's Speedmaster Chronoscope, reference 522.60.43.51.02.001, is a chronograph cased in 43 mm of yellow gold. The case measures 13 mm thick with a lug-to-lug of 48.6 mm, and the silver dial sits under a sapphire crystal with anti-reflective treatment on both sides. Inside is the manual-winding calibre 9909, a column-wheel chronograph movement with a Co-Axial escapement and a silicon balance-spring, certified as a Master Chronometer and resistant to magnetic fields up to 15,000 gauss. Two barrels mounted in series give it 60 hours of power reserve. The dial layout adds a tachymeter scale and small seconds counter alongside the chronograph functions. The bracelet is yellow gold with a foldover clasp. This reference carries a water resistance of 50 metres.
