Measuring 49.94 × 44.50 mm, the RM 53-01's Carbon TPT case and matching Carbon TPT bezel form the structural foundation for one of Richard Mille's most mechanically ambitious calibers. The laminated, impact-resistant sapphire crystal shields the movement from the kinds of shock loads generated during professional polo play, while a screw-locked crown keeps the case secured during active wear.
Inside, the manual-winding Caliber RM53-01 delivers a tourbillon suspended via a cable architecture — a construction that sets it apart from conventional tourbillon designs and remains visible through the fully skeletonized dial. The movement offers hours, minutes, and an approximately 70-hour power reserve. The open dial allows the suspended tourbillon to take center stage, viewable from the front through the sapphire crystal.
This example is offered pre-owned and comes fitted on a rubber strap with a folding clasp. The RM 53-01 Pablo Mac Donough is among the more seldom-encountered references on the secondary market, combining the Carbon TPT construction and cable-suspended tourbillon architecture in a watch conceived as much for demanding physical activity as for horological distinction.
