The Richard Mille RM025 Tourbillon Chronograph Diver's case, developed as a secure water-tight construction, also boasts intricate workmanship. The case is crafted from a successful combination of red or white gold and titanium. It demonstrates a tripartite structure fixed with help of torque screws to guarantee a remarkably precise and even pressure-sealing.
The unidirectional rotating bezel is worth special attention - it has three layers connected with a 24-screw system. The bezel system is screwed to the case, so it is absolutely stable and reliably protected from inadvertent dislocating or loosening. The unique screw system also gives an advantage of perfect adjustment, with the bezel not tensioned into position.
The impressive water resistance is also explained by a screw-down crown and newly-designed watertight chronograph pushers.
The Richard Mille RM 025 accommodates the exclusive Richard Mille Caliber 025 that appeared as a result of extensive research and development that lasted more than five years. The RM 025 caliber has been designed to guarantee ease of serviceability and utmost performance under most demanding conditions.
The hand-wound movement incorporates a column-wheel chronograph with a one-minute tourbillon provided with a variable-inertia balance beating at 21,600 vibrations per hour. The movement also provides a torque indicator showing the optimum mainspring tension curve, a 70-hour power reserve indicator and a selector of functions to choose between "neutral", "winding" and "hand-setting".
The caliber features a number of meticulously-engineered details, including friction-diminishing titanium components incorporated by the chronograph control, specialized tooth profiles, and an in-line design of the escapement for reduced friction.
The Richard Mille RM 025 Tourbillon Diver's watch will be produced in an extremely limited number per year, considering its complexity and intricate craftsmanship.
The timepiece is coupled with a specially designed rubber diverís strap.
