This latest model of the manual-winding Speedmaster features a coaxial escapement, replacing the Cal. 1861 movement that has long been featured in the Speedmaster Professional series, and employs non-magnetic materials for its components, achieving ultra-high magnetic resistance up to 15,000 gauss. Not only does it offer high magnetic resistance, but it also meets the static accuracy standard of 0-+5 seconds per day, earning it Master Chronometer certification.
