The Richard Mille RM 52-05 Tourbillon Pharrell Williams is a highly exclusive timepiece limited to 30 units, designed in collaboration with the artist Pharrell Williams. The watch is defined by its striking dial, which depicts a first-person view of Earth as seen from the surface of Mars, reflected in the visor of an astronaut’s helmet. This scene is achieved through a combination of high-tech materials and traditional crafts, including a Grade 5 titanium helmet and an enameled red gold visor that captures the Martian landscape. The movement’s baseplate and bridges are also crafted from Grade 5 titanium, featuring blue aventurine glass inserts to represent a star-filled cosmos.
Mechanically, the RM 52-05 is powered by a manual-winding tourbillon movement that provides a power reserve of approximately 42 to 55 hours and operates at a frequency of 21,600 vph. The watch is housed in a tonneau-shaped case measuring 49.94mm by 42.35mm with a thickness of 16.15mm. While the standard RM 52-05 features a brown Cermet case with Carbon TPT casebands, certain limited iterations utilize clear sapphire for the case material. The watch is water-resistant to 30 or 50 meters, depending on the specific case construction, and typically comes paired with a high-performance rubber or alligator strap.
General reviews of the RM 52-05 emphasize its role as a pinnacle of horological art, praising the intricate enamel work and the successful translation of a personal, creative vision into a complex mechanical object. The watch is frequently lauded for its innovative use of materials, such as Cermet and Carbon TPT, which offer a unique balance of lightness and durability. However, some critics note that the highly artistic and dense dial design can make it less legible for traditional timekeeping. Despite its polarized aesthetic, it is widely regarded as a significant collector’s piece due to its extreme scarcity and the depth of its collaboration.
