Richard Mille RM 70-01 Super Clone: Tourbillon Alain Prost Cycling Edition

Asymmetric Cyclist's Tonneau: 50.23mm Angled for In-Saddle Viewing

The Richard Mille RM 70-01 super clone carries an asymmetric tonneau case measuring 50.23mm long by 47.78mm wide and 15.83mm thick, machined to the angled silhouette Richard Mille engineered for cyclists. The case pitches the dial plane toward the rider's line of sight when the hands grip the drops, which is the practical purpose of the asymmetric build. Six grade 5 titanium spline screws secure the bezel to the caseband, and the crown sits at 4 o'clock with the mileage counter reset pusher integrated into the same crown housing. The case seals the movement to 50 meters of water resistance, in line with the active sport positioning of the Alain Prost edition.

Grade 5 Titanium and Carbon TPT Construction

The RM 70-01 super clone pairs grade 5 titanium for the upper bezel and caseband with Carbon TPT, a thin-ply carbon composite, for the lower case section, mirroring the bi-material construction of the 30-piece limited reference. Grade 5 titanium delivers a strong, light, corrosion-resistant frame that lets the cyclist's tonneau sit on the wrist without bulk during a long ride. Carbon TPT brings a layered, visible weave finish that absorbs shock and keeps the case in the sub-100-gram weight band that Richard Mille engineers for sport references. The combined construction follows the genuine RM 70-01 logic on weight, surface texture, and bi-material visual identity for accurate close-inspection feel.

Sapphire Crystal and Sapphire Caseback

Scratch-resistant sapphire crystal with anti-reflective coating covers the skeletonised dial and lets full light reach the open bridges and the tourbillon-style cage below. The curved sapphire follows the asymmetric tonneau profile and clears under angled light, which keeps both the time and the odometer counter readable on the bike. The sapphire caseback exposes the hand-wound skeleton clone movement from below, including the visible mainspring barrel, the gear train, and the cage architecture at 6 o'clock. The crown at 4 o'clock locks the case for the 50-meter rating, and the integrated mileage counter pusher sits flush against the caseband when not in use.

Skeletonised Dial with Tourbillon-Style Cage at 6 O'clock

The skeletonised dial of this RM 70-01 super clone shows the movement bridges, the mainspring barrel, and the gear train from the front, with no traditional dial plate covering the architecture. The tourbillon-style cage sits at 6 o'clock in the position the genuine RM 70-01 caliber places its tourbillon escapement, with the cage shape and bridge cut-outs matching the reference layout under the sapphire. On the replica build the cage is engineered to resemble the genuine tourbillon visual signature, not to function as a true tourbillon escapement. Buyers receive the open-dial Richard Mille identity at a fraction of the original price.

Odometer-Style Mileage Counter at 12 O'clock

The RM 70-01 reference is the only Richard Mille wristwatch to integrate a mileage counter, and the super clone follows that signature layout with an odometer-style module at 12 o'clock. The module displays a rotating-disc mileage readout in the same position the genuine caliber places its integrated counter, with a crown-mounted reset detail on the case flank. On the replica build the counter is a decorative module rather than a working mechanical mileage mechanism. The 12 o'clock placement, the disc shape, the surround finishing, and the matching skeleton aesthetic all track the visual identity of the genuine Alain Prost reference.

Applied Branding, Hands and Tonneau Legibility

The dial carries applied "Richard Mille" branding on the upper bridge and applied "Alain Prost" branding at the 9 o'clock zone, in the same gold-and-white palette Richard Mille uses for athlete-signature references. The skeleton hour and minute hands run in skeletonised baton form, matching the open architecture and giving a clear time reading against the visible bridges. The asymmetric tonneau case extends the dial vertically and angles the read plane, which keeps the hour, minute, and odometer counter visible when the wrist sits in cycling position. The chapter ring carries minute markers around the outer edge for precise reading.

Swiss-Grade RM 70-01 Clone Hand-Wound Skeleton Movement

The Richard Mille RM 70-01 super clone runs on a Swiss-grade hand-wound mechanical skeleton movement engineered to match the genuine Richard Mille RM 70-01 caliber in feel, frequency, and architectural look. The movement operates at 21,600 vibrations per hour, winds by hand through the 4 o'clock crown, and holds a power reserve of approximately 70 hours for nearly three days off the wrist. The caliber drives the central hours and minutes across a grade 5 titanium baseplate and bridges, the same architectural choice the genuine RM 70-01 uses for shock resistance, low weight, and high rigidity. The cage at 6 o'clock and the mileage module at 12 o'clock are engineered to mirror the genuine reference layout, with the cage built as a visual tourbillon-style component and the mileage module built as a decorative odometer-style disc.

Accuracy, Shock Resistance and Cycling Daily Performance

Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer band a Swiss-grade hand-wound build supports. The grade 5 titanium baseplate and bridges give the movement a strong, light core that handles shock during cycling and outdoor sport, which is the architectural reasoning behind the genuine RM 70-01 build. The 50-meter water resistance and the screw-down crown at 4 o'clock seal the movement against rain, sweat, and hand washing, in line with the all-weather cyclist positioning of the Alain Prost edition. The decorative cage at 6 o'clock spins as a visual element and does not affect rate accuracy, since the regulating organ sits on the standard balance wheel of the clone caliber.

Black Rubber Strap and Titanium Deployant Buckle

The RM 70-01 super clone carries a black rubber strap, the strap style Richard Mille pairs with the Alain Prost cycling reference. The strap uses a soft, flexible rubber compound that holds its shape across long-term wear, with integrated lugs that flow into the asymmetric tonneau case for the continuous Richard Mille silhouette. A grade 5 titanium deployant buckle closes flush against the wrist for a secure hold during a ride, and the strap material clears sweat and water with a quick wipe. The Alain Prost edition uses the black rubber strap on this cycling variant and not a metal bracelet, in line with the genuine sport-collaboration spec.

Wrist Feel, Sizing and Comfort on the Bike

The watch weighs approximately 95 grams on the full black rubber strap, which gives the RM 70-01 the light wrist presence Richard Mille engineers for endurance use. The 50.23mm by 47.78mm asymmetric tonneau case wears closer to a 44mm round watch on the wrist due to the curved geometry, and the 15.83mm height clears most cycling glove cuffs. The angled case plane tilts the dial toward the rider's eye line when the hands grip the drops, which the genuine Alain Prost edition was engineered to solve. The RM 70-01 super clone sits comfortably on wrists from 6.5 to 8 inches with the titanium deployant buckle adjusted across the strap holes.
