Richard Mille RM 055 Super Clone Bubba Watson Japan Blue White Ceramic Skeleton Dial

Tonneau Case Geometry 49.94mm White ATZ Ceramic Asia LE Build

The Japan Blue edition of the RM 055 Super Clone carries a tonneau case measuring 49.94mm long by 42.70mm wide and 13.05mm thick, machined to the curved Richard Mille profile that the Bubba Watson reference defined for the brand's golf collaborations. The upper bezel and the caseback ring use white ATZ ceramic, while the central caseband uses grade 5 titanium for structural strength. Six polished titanium spline screws ring the bezel and tie the upper ceramic, the titanium caseband, and the lower ceramic ring into the three-piece sandwich construction Richard Mille uses across its sports references. The screw-down crown sits at 2 o'clock and seals the case to 50 meters of water resistance.

White ATZ Ceramic, Grade 5 Titanium and Spline Screw Construction

The white ATZ ceramic bezel and caseback ring deliver a hard, scratch-resistant surface that holds its bright white colour across years of wear without yellowing or surface dulling. ATZ ceramic, an alumina-toughened zirconia composite, ranks among the hardest engineered materials in modern watchmaking and gives the Asia LE case the matte white finish that frames the blue dial accents. The grade 5 titanium caseband supplies a strong, light spine that keeps the watch under 100 grams on the rubber strap, and the six titanium spline screws are torqued in sequence to maintain even pressure across the ceramic-titanium-ceramic stack. This super clone follows the genuine three-layer Asia LE construction so the watch reads correctly on weight balance, surface texture, and edge geometry.

Sapphire Crystal and Sapphire Display Caseback

Scratch-resistant sapphire crystal with anti-reflective coating covers the skeletonised dial and lets full light reach the blue-toned bridges below. The curved sapphire follows the tonneau silhouette and stays clear under angled wrist light, a feature collectors look for on the Asia LE because the blue accents read differently across lighting conditions. The sapphire display caseback shows the hand-wound clone movement from below, including the visible mainspring barrel, the gear train, and the satin-finished titanium bridges, and the screw-down crown supports the 50-meter water-resistance rating across daily wear.

Skeletonised Dial with Japan Blue Bridge Accents

The skeletonised dial of the Japan Blue 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 defining feature of the Asia limited edition is the deep blue tonal accent applied across the visible bridges, which gives the open dial a cool blue glow against the white ceramic frame. This blue colourway separates the Japan Blue from the standard white ceramic Bubba Watson production, which carries neutral titanium bridges, and the super clone matches the bridge tone, the cut-out shape, and the open architecture of the genuine Asia release.

Gold-Toned Hour Markers and Applied Richard Mille Branding

The Asia LE carries applied gold-toned hour markers placed around the chapter ring, with the applied "Richard Mille" branding on the upper bridge in the same gold finish. The gold marker and logo treatment plays against the blue bridges and the white ceramic frame for a three-colour palette that defines the Japan Blue against every other RM 055 variant. The skeleton hour and minute hands run in skeletonised baton form with luminous fill, giving a clear time reading against the blue bridges, and the central seconds hand reads in the same skeleton style for visual consistency.

Tonneau Layout and Three-Colour Legibility

The tonneau case shape extends the dial vertically and gives the skeletonised display extra real estate for the visible blue-toned movement architecture. The gold markers stay legible against the blue bridges through the warm-cool colour contrast, and the chapter ring carries the printed minute track around the outer edge for precise reading. The white ceramic bezel frames the dial without colour interference, which keeps the focus on the blue bridges and gold markers underneath. The three-colour interplay of white ceramic, gold markers, and blue bridges is the visual signature of the Japan Blue Asia LE and the reason the variant carries a price premium over the standard ceramic Bubba Watson on the genuine market.

Swiss-Grade RMUL2 Clone Hand-Wound Skeleton Movement

The Japan Blue Super Clone runs on a Swiss-grade hand-wound mechanical movement engineered to match the genuine Richard Mille RMUL2 caliber on feel, frequency, and architecture. The movement operates at 21,600 vibrations per hour, winds by hand through the 2 o'clock screw-down crown, and holds a power reserve of approximately 55 hours for over two days off the wrist. The caliber drives the central hours, minutes, and seconds across a grade 5 titanium baseplate and satin-finished titanium bridges, the same architectural choice the genuine RMUL2 uses for shock resistance and weight reduction. The Asia LE production applies a blue surface treatment to the bridge tops for the Japan Blue colourway, which the super clone replicates through a matching blue PVD-style finish.

Accuracy, Shock Resistance and Daily Performance

Daily deviation holds within -5 to +8 seconds per day after factory regulation, close to the chronometer band that buyers expect from a Swiss-grade hand-wound build. The grade 5 titanium baseplate and bridges give the movement a strong, light core that handles shock during sport use, which is the architectural reasoning behind the genuine RMUL2 in the original Bubba Watson signature. The 50-meter water resistance and the 2 o'clock screw-down crown let the Japan Blue Super Clone hold its seal through daily wear, hand washing, and light water contact, in line with the active-wear positioning of the RM 055 line.

White Rubber Strap with Blue Accent Stitching

The Japan Blue Super Clone ships with a white rubber strap finished with blue accent stitching that matches the dial bridge colourway, the strap configuration Richard Mille paired with the Asia limited edition. The strap uses a soft, flexible rubber compound that holds its shape across long-term wear, with integrated lugs that flow into the tonneau case for the continuous Richard Mille silhouette. The blue stitching runs along both edges of the strap and ties the white-blue-gold dial palette down through to the wrist, which is the defining strap detail that separates the Japan Blue from the standard white ceramic Bubba Watson. The Asia LE uses this white-with-blue rubber strap and not a plain white or all-blue strap.

Titanium Deployant Buckle and Wrist Feel

A grade 5 titanium deployant buckle closes flush against the wrist for a secure hold and lets the buyer remove the watch without flexing the strap repeatedly. The titanium clasp keeps the weight low and matches the caseband material for a unified metal palette. The watch weighs approximately 92 grams on the full white rubber strap, which gives the Japan Blue the light wrist presence buyers expect from a ceramic-and-titanium Richard Mille. The 49.94mm by 42.70mm tonneau case wears closer to a 44mm round watch on the wrist due to the curved geometry, and the slim 13.05mm height clears most shirt cuffs. The Japan Blue Super Clone sits comfortably on wrists from 6.5 to 8 inches with the deployant buckle adjusted across the strap holes.
