Richard Mille RM055 Blue 43mm Men Manual Watch

For collectors, the Richard Mille RM055 is never judged in isolation. It is almost always compared against nearby references in the brand’s sports catalog: heavier-looking variants, darker executions, louder colorways, or technically similar openworked models that sit just a step away in price and personality. That is what makes this blue RM 055 especially interesting. Rather than trying to be the most aggressive sibling in the lineup, it positions itself as the more visually open, cooler-toned, and easier-to-read interpretation of the Bubba Watson formula.

This is a **men’s sports watch** with a **manual-wind mechanical movement**, and that matters immediately. The RM055 wears like an active Richard Mille, but it presents itself like a collector’s piece first: exposed mechanics, a transparent tonneau case, and a blue chapter ring that changes the mood versus more monochrome sibling references. Where some RM sports models lean into stealth, this one leans into display.

Transparent tonneau case and blue strap view.

The first point of differentiation is the case. The watch shown here uses a transparent tonneau-style case that gives the RM055 a lighter visual footprint than opaque siblings. Richard Mille collectors often compare references by how much of the architecture they reveal from the wrist. On that scale, this piece stands out. The bezel screws, layered construction, and curved side profile are still unmistakably RM, but the transparency adds a more technical, almost display-case quality. It frames the movement rather than merely housing it.

That ergonomic curve is central to the RM055 identity. Even among tonneau watches, Richard Mille cases are designed to sit close to the wrist, and this example shows that familiar arched profile clearly. For a sports watch, comfort is part of collectability. Sibling references may share the same visual DNA, but the RM 055 has long been appreciated for being one of the more direct, wearable entries into the brand’s athletic design language.

The blue chapter ring is the detail that gives this version its own voice. On many skeletonized Richard Mille watches, the eye goes first to the bridges and balance of negative space. Here, the blue ring creates a strong perimeter, helping structure the dial visually. It is not a full blue dial in the traditional sense; instead, it acts as a color frame around the openworked center. That distinction matters for collectors choosing between sibling references. A full-color execution can sometimes dominate the watch. A colored chapter ring, by contrast, adds personality without covering the mechanical core.

The skeletonized dial itself remains the heart of the watch. The RM055 is known for its openworked presentation, and the visible manual-wind movement is exactly why many buyers step toward this reference instead of an automatic alternative from the broader luxury sports field. There is no rotor interrupting the view. The architecture is direct, exposed, and mechanical in the old-school sense, even though the design language is distinctly modern Richard Mille. Large numerals, visible bridges, and the sense of suspended components all contribute to that effect.

That manual-wind format also shapes collector positioning. Within Richard Mille, some references attract attention for complications, others for case material, and others for celebrity association. The RM 055 often holds its ground because it offers a purer interaction: wind the watch, observe the movement, enjoy the lightness and shape on the wrist. Compared with sibling references that add more visual density or technical layers, the RM055 can feel more focused. It is sporty, but not cluttered.

Visible mechanics remain the focus of the watch.

The blue rubber strap reinforces that focus. Rubber is expected in this category, but color-matched rubber changes the tone of the watch significantly. A black strap would make the piece more severe and more familiar within the Richard Mille universe. Blue softens the watch visually while keeping the athletic character intact. For collectors comparing siblings, that means this RM055 can bridge two roles better than many variants: it still reads as a high-performance sports piece, yet it looks less tactical and more curated.

Blue rubber strap ties the whole design together.

Another reason this watch stands apart is balance. Transparent case, exposed movement, bright ring, and blue strap could have produced visual overload. Instead, the layout stays coherent because the RM055 base design is already highly structured. The tonneau form, screw-set bezel, and suspended dial architecture keep everything disciplined. That is an advantage over sibling references that may push color harder or add busier case textures. This watch feels edited.

From a collecting perspective, this makes the watch attractive for buyers who want a Bubba Watson-associated RM without defaulting to the most expected look. The RM 055 name already carries strong recognition in Richard Mille circles. Choosing a blue-accented, transparent-case presentation gives that known reference a fresher edge. It signals familiarity with the line, but also selectivity within it.

A cooler-toned take on the RM 055 collector favorite.

The remaining close-up images support the same conclusion: this is a watch best understood by comparison. Not because it lacks identity, but because its identity becomes stronger when placed next to its siblings. Against darker RM sports references, it looks clearer and more dimensional. Against louder colored variants, it looks more restrained. Against traditional luxury sports watches outside Richard Mille, it remains unapologetically modern.

In the end, the Richard Mille RM055 Blue 43mm men’s manual watch works best for the collector who wants a recognizable sports RM, but not the most obvious one. Its transparent tonneau case, blue chapter ring, blue rubber strap, skeletonized dial, and visible manual-wind movement create a version of the RM055 that feels cooler, cleaner, and more display-oriented than many sibling references. It is still unmistakably a Bubba Watson-line sports watch. It simply speaks in a more selective tone.
