Last month, Richard Mille’s RM 025 Tourbillon Chronograph Diver’s Watch (about $450,000) finally arrived at U.S. dealers, more than a year after it was unveiled to the world. As one would expect, Mille went to extremes with its first submersion into the dive realm. The RM 025 boasts a carbon nano-fiber tourbillon chronograph movement housed in a (notably) round tripartite case designed to stay watertight to 300 meters. Mille recently followed up with a slightly smaller (47mm) and less complicated titanium RM 028 (about $79,000) with hours, minutes, and central seconds. The RM 028 echoes the aesthetic of its audacious predecessor with a skeletonized automatic movement that includes Mille’s proprietary adjustable rotor geometry, which can be tuned to the wearer’s activity level. While the production and assembly of the RM 025 requires several months, you won’t have to wait so long to get your hands on a RM 028. (Available at Westime, 310.271.0000, www.richardmille.com)
