A diver from Richard Mille is like none other and the RM028 is no exception. The RM028 is built off the direction of the RM025 but elevates the system with a tripartite case and an ISO 6425 certification that means it meets the international standard for diving below 100 meters. The RM028 comes with a round brown PVD coated titanium case that is 47mm in diameter and 14.6mm thick with an anti-reflective sapphire crystal. The RM028 has a three-layered unidirectional rotating bezel with a double push-button safety measure which prevents inadvertent rotation during a dive. The dial is skeletonized and made of grade 5 titanium with a date window, Arabic mix hour markers and titanium hands. The RM028 is powered by the self-winding RMAS7 caliber with a variable geometry-rotor that has date functionality and a power reserve of 55 hours. The stately case is paired with an orange rubber bracelet with a titanium fold-over clasp. It has a water resistance of 300 meters (1,000 feet).
