Encased in black ceramic, this replica rm-055 225 delivers the RM-055 in a material that balances the visual depth of carbon fiber with the polished refinement that ceramic surfaces provide. The black ceramic finish can range from matte to semi-gloss depending on the production treatment, and either way it offers scratch resistance that outlasts both steel and titanium under regular wearing conditions. Richard Mille has used black ceramic across multiple RM references, and the 49.9 x 42.7mm tonneau case gives the material enough surface area to show its character.

Key Specifications

• Case material: black ceramic (zirconium oxide)
• Dial: skeletonized or semi-open
• Crystal: sapphire with anti-reflective coating
• Strap: rubber with titanium buckle
• Movement: automatic
• Water resistance: 50m

Black ceramic achieves its color through the sintering process itself, not through surface coating. This means the color is integral to the material and cannot wear away, chip, or fade over time, unlike PVD or DLC treatments applied to metal cases.

Design & Finishing

Where NTPT carbon fiber cases show visible grain patterns, black ceramic presents a more uniform surface that reads as cleaner and more refined at arm’s length. The visual effect is darker than most carbon fiber treatments and more consistent edge to edge. The rubber strap continues the dark theme while keeping the watch comfortable for prolonged wear. For a comparison point within the same reference, the V2 skeleton dial edition uses a different case material and opens the dial further. Both sit in the RM-055 lineup, but the black ceramic version trades material texture for material uniformity.

On the Wrist

Ceramic weighs less than steel and stays thermally neutral on the skin, which means no cold shock when you put it on in the morning. The scratch resistance means the case looks the same after twelve months of daily wear as it did on day one. This replica rm-055 225 gives collectors a black ceramic option that combines the RM-055 tonneau profile with a case material built for durability and long-term visual consistency.
