A highly complex sports timepiece, a masterpiece of technical prowess designed for everyday use and for any situation, such is the latest execution of Richard Mille’s tireless quest for innovation, the new RM 65-01. The culmination of some five years of development, this automatic split-seconds chronograph is the most complex timepiece ever to leave the Richard Mille workshops. This model fully embodies the brand’s technical approach thanks to the combination of several additional functions, a very specific architecture and an extremely high-end aesthetic. All in all, a fabulous challenge of mechanical watchmaking that called for patience, technicity and utter perseverance. The modern architecture of this movement enables for the consistent and rational arrangement of its constituent parts, avoiding unnecessary superimpositions and permitting the best possible use of the functions thanks to technical solutions. The RMAC4 calibre is equipped with the latest-generation split-seconds mechanism developed by the engineers at Richard Mille. The 6-column wheel ensures optimised simultaneous movement, maximal function locking, and greater adjustment durability.
