This December, the story of that watch continues on the sands of Miami Beach, as Rado joins the 2025 edition of the Untitled Art with a dedicated exhibition that celebrates the DiaStar and its bold, genre-defying reinvention.

Running from December 2nd to 7th, Untitled Art has built a reputation as one of the most progressive platforms in the art calendar It transcends the conventional model of an art fair, offering a dynamic, curator-driven environment designed to foster dialogue, inclusivity, and artistic evolution. This makes it a fitting backdrop for Rado, long known as the “Master of Materials”, to present one of its most striking collaborations, the DiaStar Original x Tej Chauhan.

On December 3rd, visitors to the Rado space will have the rare opportunity to meet Rado CEO Adrian Bosshard and designer Tej Chauhan in person. Their presence speaks to the shared vision behind this limited edition, which is rooted in creative exchange, technical exploration, and the expressive use, and celebration of, colour.

A new chapter in a Rado icon

When the Rado DiaStar was first introduced in 1962, it was described as the world’s first scratchproof watch. With its faceted crystal, futuristic form, and use of hardmetal, it felt decades ahead of its time. In many ways it was. Over the years, the DiaStar became a hallmark of the brand’s commitment to material innovation. It was also a bold statement piece that is both unconventional and confident, whilst being resolutely uncompromising.

The DiaStar Original x Tej Chauhan takes that legacy and casts it in a new, 21st century context. Designed in collaboration with the British industrial designer best known for his “Emotive Industrial Design” philosophy, this 38mm timepiece is a study in contrasts. Softness and strength, simplicity and detail, what was and what could be.

Its polished yellow gold-coloured PVD-coated Ceramos™ bezel, made from Rado’s proprietary ceramic-metal composite, frames a concave matt black dial that feels sculptural yet minimal. The minute track, printed in silver or blue, has a visual effect, not unlike the Millenium Falcon jumping to hyperspace, with a true dimensionality to the layout. Most striking of all is the day-date display at three o’clock, rendered in Chauhan’s own custom font and using a different colour for each day of the week. “It represents the way I feel the week,” Chauhan explains, a small but powerful gesture that plants a seed of humanity in the high-tech world of modern watchmaking.

The case back is engraved to commemorate the collaboration, while the grey, pillow-shaped rubber strap and bespoke folding clasp complete the watch’s rounded, tactile aesthetic. Powering this futuristic flashback is the Rado calibre R764, an automatic movement with 80 hours of power reserve and a Nivachron™ hairspring that offers robust resistance to magnetic fields, proof that this watch is as technically sound as it is visually distinctive.

Material thinking and emotional form

For Rado, this collaboration with Chauhan continues a long-standing dialogue between horology and design. Over the past decades, the brand has worked with more than thirty artists and designers across different disciplines, each bringing a new voice to the core values of the brand.

Known for its pioneering use of materials, from high-tech ceramic to Ceramos™, Rado has always treated design as a tool for storytelling. This isn’t innovation for its own sake, it’s about creating objects that connect. “Design you can feel” isn’t just a slogan; it’s a philosophy.

Chauhan’s approach to design aligns perfectly with that. His work, spanning product development, brand strategy, and creative direction, is rooted in form, colour, and tactility. Based between London and Helsinki, Chauhan leads a team of designers who focus on creating objects that spark joy and engagement. “We’re interested in how people respond emotionally to design,” he explains. “Shape, material, and colour aren’t just aesthetic choices; they invite interaction.”

That ethos is visible throughout the DiaStar Original x Tej Chauhan. From the curved rubber strap to the warm gold tones of the bezel, the watch encourages both visual appreciation and physical connection. It’s a piece that looks different on each wrist, and different again depending on the day of the week.

A watch made for this moment

In the context of Miami Beach’s Untitled Art, a space that celebrates experimentation and creative dialogue, the DiaStar Original x Tej Chauhan feels perfectly placed. It’s a watch that speaks to the present in both form and spirit: collaborative, playful, and emotionally engaging.

More than just a product, the DiaStar Original x Tej Chauhan reflects Rado’s belief that even the most technical objects can be personal. At a time when much of watchmaking looks to the past, it is a reminder that innovation also shapes legacy.

As Rado continues to embrace new materials, new perspectives, and new ideas, one thing remains constant; a commitment to design you can feel.
