Showcasing an open-worked dial, this replica rm-035 skeleton from BBR Factory puts the automatic movement on full display through the RM35-01 tonneau case. The skeleton treatment removes material from the dial to expose the gear train, balance wheel, and winding rotor in a layered arrangement that turns the watch face into a mechanical landscape. Richard Mille has always embraced transparency in the RM-035 series, and the full skeleton configuration pushes that philosophy to its visual extreme. At approximately 49.94mm by 44.50mm, the tonneau case provides more surface area for the skeleton architecture than a round case of similar diameter would offer.

Technical Overview

• Case dimensions: approximately 49.94 x 44.50mm (tonneau shape)
• Case material: composite construction
• Bezel: fixed
• Crystal: sapphire with anti-reflective coating (front and back)
• Strap: rubber with folding clasp
• Movement: automatic, fully skeletonized
• Functions: hours, minutes, seconds

BBR Factory applied the skeleton work to both the front dial aperture and the caseback, creating a see-through effect where ambient light passes through from one side to the other. The hands are mounted on thin posts above the movement to maintain legibility.

Inside the Movement

Full skeletonization demands careful finishing because every surface is visible. Rough tool marks or uneven edges would break the visual illusion. The bridges show alternating brushed and polished zones that create contrast between structural and decorative areas. The automatic rotor spins freely at the back of the movement, visible through the caseback window. For a version that obscures some of this mechanical detail behind a more conventional dial, compare against the America5 reference which balances openness with readability. Both options live within the RM-035 collection, but they serve different priorities on the spectrum between horological display and everyday legibility.

What Sets It Apart

Skeleton watches attract a specific audience: people who buy watches partly to admire the engineering. The RM35-01 tonneau shape amplifies that appeal by offering a larger window into the movement than most round-cased skeleton pieces. Under direct light, the layered components create shadows and reflections that change throughout the day. This replica rm-035 skeleton from BBR Factory turns the RM35-01 into a wearable demonstration of mechanical watchmaking for anyone who values visual access to the movement above all else.
