Richard Mille RM27-02 Sapphire Crystal Tourbillon Clone

RM27-02 Sapphire Crystal Tourbillon Clone Overview

The RM27-02 Sapphire Crystal Tourbillon Clone represents one of the boldest expressions of modern watchmaking, combining extreme transparency with ultra-light engineering. Its full sapphire crystal case delivers a floating visual effect, allowing the movement to appear suspended in mid-air while revealing every gear, bridge, and torque component in exquisite detail. This model has become an icon for collectors who appreciate futuristic aesthetics paired with mechanical sophistication.

Full Sapphire Crystal Case & Advanced Construction

The signature element of this RM27-02 interpretation is the clear sapphire crystal case. Crafted through high-precision CNC machining, the case is sculpted from synthetic sapphire blocks that offer exceptional hardness and optical purity. Unlike conventional transparent materials, sapphire is virtually scratch-proof and retains its clarity even after years of wear. The entire case structure—including the bezel, middle case, and caseback—is shaped to echo Richard Mille’s ergonomic tonneau form, ensuring a comfortable wrist presence despite its technical complexity.

Suspended Skeleton Movement

Inside the transparent case lies a dramatically open-worked mechanical movement. The skeleton bridges, ultra-slim arms, chamfered edges, and exposed gear train create a stunning architectural depth. The calibre appears “floating” thanks to the use of a tension-support system inspired by RM’s iconic tourbillon engineering. The transparent case amplifies the visual effect, allowing light to flow through the entire movement and illuminate every mechanical detail from multiple angles.

The balance wheel, tourbillon cage, and mainspring barrel operate with smooth precision, delivering reliable performance while showcasing the artistry behind high-end mechanical design.

High-Tech Sapphire & Titanium Integration

To ensure durability within a transparent case, the clone features grade-5 titanium screws, reinforced movement anchors, and vibration-absorbing mounts. These materials mirror the approach used in advanced sports engineering, offering stability and long-term resilience. The result is an ultra-light yet structurally sound watch that performs comfortably during everyday use.

Anti-Reflective Visibility

Both the front and back sapphire surfaces include anti-reflective coatings that reduce glare and maintain excellent clarity under strong lighting. This ensures the skeletonized movement remains visually accessible, whether indoors or outdoors.

Comfort-Focused Strap Design

Each version of the RM27-02 Sapphire Crystal Tourbillon Clone is paired with a soft, skin-friendly rubber strap. The strap’s flexibility and texture create a natural wrist fit, enhancing comfort despite the watch’s sculptural aesthetic. Its color options—including black, white, and custom colors—allow you to express different styles while maintaining the futuristic theme of the sapphire case.

Water Resistance & Care Recommendations

Although the case construction is precise, sapphire-case watches require thoughtful usage. The RM27-02 Sapphire Crystal Tourbillon Clone includes practical water-resistance support for daily wear and light moisture exposure. To protect the watch:

• Avoid steam rooms, hot water, or rapid temperature changes.
• Rinse with fresh water after sea exposure and dry with a soft cloth.
• Keep the crown securely tightened before contact with moisture.
• Schedule periodic gasket inspections to maintain long-term resistance.

These precautions help ensure clarity, structural stability, and long-term performance.

A Statement Piece of Modern Engineering

The RM27-02 Sapphire Crystal Tourbillon Clone is more than a transparent mechanical watch—it is a celebration of futuristic craftsmanship and advanced materials. Its sapphire case, floating skeleton movement, and ultra-light construction embody the spirit of experimental haute horlogerie. For collectors seeking a visually striking timepiece that merges innovation with bold aesthetics, this model delivers a dramatic and unforgettable wrist presence.
