Incredibly-Detailed: Richard Mille Automatic RM 023

This is the new masterpiece of Richard Mille – the RM 023 – another high class model of perfection made in Switzerland.

With a power reserve of 55 hours and measurements of 45.00mm (length) x 37.80 mm x 11.25 this skeletonized watch is based on the highest level of technique and design. The dial of the RM 023 has an unique asymmetrical layout, in which the large Roman numerals are integrated into sapphire glass. Richard Milles Automatic RM 023 is a watch which embodies high class materials such as a minute flange in black carbon fiber or diamond polished sinks on the bridge side. 68 different stamping operations are required for the three main components, the bezel, the middle section and the case back. Many sections are polished by hand such as the locking sections or the anglages. For further details check out the details below….

MAIN FEATURES

(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)

POWER RESERVE

Circa 55 hours.

ROTOR WITH VARIABLE GEOMETRY

– Arm in grade 2 titanium
– Flange in grade 2 titanium
– 6-positional adjustment via grade 5 titanium screws
– Wings in 18-carat, high palladium content white gold
– Weight segment in tungsten/cobalt alloy
– Ceramic ball bearings
– Unidirectional; anti-clockwise winding direction

This exclusive RICHARD MILLE design allows the rewinding of the mainspring to be adapted most effectively to the user’s activity level within sports or leisure environments. By adjusting the six positional setting of the rib’s placement, the rotor’s inertia is modified, either speeding up the winding process in the case of minimal arm and hand movements, or slowing it down when high activity sports are pursued. As a result, this invention allows the movement’s winding mechanism to be optimized and personalized to the owner’s lifestyle.

BASEPLATE, BRIDGES AND BALANCE COCK MADE OF TITANIUM

The manufacture of these components in grade 2 titanium with black PVD coating allows the whole assembly to be given great rigidity, as well as precise surface flatness which is essential for the perfect functioning of the gear train. The skeletonized baseplate was subjected to separate and extensive validation tests to insure optimal strength requirements.

DOUBLE BARREL SYSTEM

The double barrel system helps improve torque stability over a longer period.
This is achieved by utilizing more turns of the barrel, thereby reducing pressure and wear on the teeth, bearings and pivots, resulting in improved long-term performance.

DATE DISPLAY

Semi-instantaneous, placed vertically near the Roman numeral VII. The calendar disc of sapphire crystal is treated with non-reflective coating on both sides.

SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE

This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

OTHER FEATURES

– Movement dimensions: 30.25 x 28.45 mm x 4.33 mm
– Number of jewels: 32
– Barrel arbor – in AP 20 steel
– Balance: GLUCYDUR, 4 arms, inertia moment 4.8 mg.cm2, angle of lift 53o
– Frequency: 28,800 vph (4 Hz)
– Balance spring: ELINVAR NIVAROX
– Index assembly: Triovis N°2
– Shock protection: INCABLOC 908.22.211.100 (transparent)
– Escapement wheel jewels: Rubifix (transparent)
– Stem with three positions: manual winding, time setting and date adjustment

WATCHCASE WITH IMPROVED FUNCTIONALITY

This was the subject of an entire year of research and development. With regard to the production
of each case, 68 different stamping operations are required for the three main components (bezel, middle section and case back). The machine tooling process requires 8 days of adjusting the machines for the bezel, 5 days for the middle section and 5 days for the case back. Prior to this process, develo- ping a methodology for carrying out this series of operations took 120 hours, the drawings for the tools 130 hours, and implementation 180 hours. Each rough case involves 202 separate machining operations. The design and execution of the watch demonstrates a complete conceptual approach to the movement, case and dial. As a result, everything has been constructed according to an extremely rigorous specification, in the manner of the analytical engineering methods used in the design of Formula 1 racing cars where the chassis and the engine are developed in complete harmony.

For example, a casing ring is no longer used and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by 4 titanium screws. Features such as these are evidence of uncompromising workmanship. The tripartite case is water resistant to 50 meters, ensured by three Nitril O-ring seals. The case is assembled with 12 spline screws in grade 5 titanium and abrasion resistant washers in copper-nickel-zinc alloy.

CROWN

In grade 5 polished titanium, with double seal O-ring and collar in Alcryn.

DIAL

In sapphire (thickness: 0.40 mm) with anti-glare treatment (both sides), protected by 8 silicon braces inserted in the upper and lower grooves.

CRYSTAL

Bezel side: In sapphire (1800 Vickers) with anti-glare treatment (both sides). Thickness: 1.20 mm
Case back: In sapphire with anti-glare treatment (both sides).
Thickness: at the center 1 mm and outer edges 1.73 mm

INTERIOR FLANGES

Upper flange in white carbon fiber, the index points filled with approved luminous material; minute flange in black carbon fiber.
