Richard Mille RM 055 Bubba Watson Green 43mm Men Manual Watch

The Richard Mille RM 055 Bubba Watson is the kind of men’s manual-winding sports watch that can look extreme in photos yet feel surprisingly considered on the wrist. For this specific transparent green version, the real conversation is not only the openworked movement or the bold tonneau case. It is how the watch manages strap, clasp, crown access, and case curvature to make such an assertive design more wearable in daily use than many people expect.

Richard Mille introduced the RM 055 “Bubba Watson” in 2012 in association with professional golfer Bubba Watson, and the model has always carried a strong performance identity. That sporting purpose matters here, because comfort is not separate from design. On the RM 055, ergonomics are built into the shape. The curved case profile, the integrated way the strap meets the case, and the soft white rubber strap all work together to reduce the visual and physical bulk that a technical tonneau watch can otherwise create.

Transparent green tonneau case overview.

The transparent green tonneau case gives this RM 055 a very different wrist presence from ceramic or darker composite executions. Green can often read loud, but the transparency changes the effect. Instead of appearing heavy, the case feels lighter because light moves through it. That visual lightness pairs well with the white strap, which keeps the watch from becoming too dense or top-heavy in appearance.

Comfort starts with the case profile. The RM 055 is known for its tonneau-shaped construction, and this example shows how the curve helps the watch sit closer to the wrist. A flat case of similar dimensions would fight the wrist and create pressure points at the lugs or strap ends. Here, the case bends with the arm. That matters on a sports watch, especially one with a substantial visual footprint. Even before discussing the clasp, this curvature is the first reason the watch looks more wearable than its size suggests.

The oversized crown also plays into usability. On many large sports watches, a prominent crown can dig into the back of the hand. In this design, the placement and the overall contour of the case help reduce that issue. The crown remains easy to grip for winding the manual movement, which is important because this is not an automatic watch you can ignore. A manual-winding Richard Mille should make that daily interaction feel precise rather than awkward, and the oversized crown supports that ritual.

The white rubber strap is one of the strongest comfort features on this watch. On a watch with a skeletonized dial, visible gears, and an unconventional case material appearance, the strap has to do practical work. White rubber softens the experience. It is flexible, it conforms quickly, and it prevents the watch from feeling overly formal or fragile. A stiffer strap would work against the curved case, but this one supports it. The result is a more planted fit with less tendency for the watch to shift around the wrist.

This is also where clasp ergonomics become important. Even when the clasp itself is not the visual centerpiece, the fit it creates defines whether a sports watch can be worn for long periods. The RM 055’s strap-and-clasp setup appears designed to keep the watch centered, which is essential on a tonneau case. A poor clasp can cause a watch to rotate or sit unevenly. On this model, the integrated feel between case and strap suggests a more balanced closure system, one that complements the architecture rather than interrupting it.

The skeletonized dial with visible gears keeps the RM 055 visually active from every angle. Richard Mille uses the RMUL2 movement family for the RM 055, a manual-winding tonneau-shaped calibre displaying hours, minutes, and seconds. That openworked layout is central to the watch’s identity. You are not looking at a decorative dial placed over a movement. You are looking into the movement architecture itself, with bridges, gears, and structural elements forming the face of the watch.

That transparency on the dial side mirrors the transparency of the green case. Together, they create a consistent design language: nothing feels closed off or unnecessarily covered. For daily wear, that matters because the watch stays interesting without relying on polished surfaces alone. The eye keeps finding new details, from the layered movement structure to the way the case edges catch light.

Another practical point about wearability is weight distribution, or at least perceived weight distribution. The RM 055 does not wear like a round, solid-dial sports watch. Its open architecture and curved build change how it occupies the wrist. The transparent green case avoids the visual compactness of darker materials, while the white strap visually extends the profile in a lighter, less abrupt way. That makes the watch feel less block-like and more integrated.

Case curvature helps the watch hug the wrist.

This is where the RM 055 Bubba Watson earns respect beyond hype. It is easy to focus on the celebrity association or the radical styling, but the better reading is functional. Richard Mille did not simply make a loud sports watch. The brand shaped a technical watch around the realities of movement, winding, and wrist ergonomics. The oversized crown is useful. The tonneau profile is purposeful. The rubber strap is not an afterthought. The comfort story is built into the watch, not added later.

The white strap balances the bold case visually.

For collectors comparing variants, this transparent green interpretation also brings a fresher, less conventional character than the earlier white ceramic and titanium executions commonly associated with the RM 055. It still feels unmistakably Richard Mille, but the green transparency gives it a more experimental edge. Importantly, that does not compromise legibility of the basic layout. The hands and movement geometry still create enough structure for the dial to read as a watch first, not just a design object.

In the end, this Richard Mille RM 055 Bubba Watson 43mm men’s manual watch stands out because it combines spectacle with wear-focused details. The transparent green tonneau case gets attention. The skeletonized RMUL2-style movement architecture delivers technical appeal. But the white rubber strap, oversized crown, curved case profile, and likely well-balanced clasp behavior are what make the watch easier to live with. For a sports watch that looks so dramatic, that everyday comfort is the more interesting achievement.
