Richard Mille RM 65-01 Automatic Split-Seconds Chronograph in Grey Quartz TPT is one of the brand’s most mechanically complex automatic timepieces. Developed over five years, the watch integrates a high-frequency split-seconds chronograph with an innovative rapid-winding system driven by a dedicated pusher at the 8 o’clock position. The distinct matte grey aesthetic is achieved by layered Quartz TPT (Thin Ply Technology), resulting in an ultra-lightweight yet incredibly durable tonneau case.
