The upgraded GMT movement is the link same cal. 3285 seen in the current GMT-Master II and comes with the more efficient Chronergy escapement, which translates to a longer power reserve of 70 hours versus 48 for the cal. 3187 seen link in the last version. It also has a Paraflex shock system, a paramagnetic link blue Parachrom balance spring, and a rotor mounted on ball bearings.
