Pre-owned Omega Speedmaster ref 310.30.42.50.01.002 is powered by the calibre 3861 movement, an upgraded version of the calibre 1861 that once powered the iconic “Moon Watch” for five decades. The innovative movement came to market in 2019 and offers the wearer such luxuries as a 50-hour power reserve, a free-sprung balance with silicon balance spring, resistance to magnetic fields up to 15,000 gauss, and the coveted distinction of a Master Chronometer. Its design set also includes the iconic black step dial adorned with an applied Omega logo, an aluminum bezel top ring, a domed and scratch-resistant sapphire crystal, a newer-style case with twisted lugs, and a silky multi-link bracelet.
