In the disciplined landscape of tool watches, where monochromatic dials and utilitarian aesthetics often reign supreme, there is a refreshing sense of rebellion in a splash of color. UNIMATIC has long been the darling of the minimalist diver scene, known for their “ghost” bezels and stripped-back Italian sensibility.
However, their latest creative venture, the UNIMATIC Modello Uno U1-RIO, takes that stern Milanese DNA and relocates it directly to the neon-soaked, sun-drenched shores of South Beach. A collaboration with the celebrated Miami photographer and creative director Cam Rio—better known as RIOCAM—this timepiece is a limited-edition masterclass in coastal energy and artistic expression.
Limited to just 300 pieces, the U1-RIO is an immediate standout for its “verde acqua” dial, a shade that perfectly captures the shifting turquoise of the Atlantic at high noon. This vibrant base is punctuated by Super-LumiNova GL Light Red markers and matte white ladder phantom hands, a color combination that echoes the cinematic, high-fashion photography for which RIOCAM is renowned.
It is a watch that feels as much like a piece of contemporary art as it does a serious piece of diving equipment. Yet, beneath the playful Miami palette, the Modello Uno remains a formidable instrument.
Housed in a 41.5mm solid 316L brushed stainless steel case, the watch is engineered for a life of adventure. It features a double-domed, anti-reflective sapphire crystal and a screw-down 8mm crown that helps achieve an impressive water resistance of 300 meters.
Powering the watch is the workhorse Japanese NH35A automatic movement, operating at 21,600 bph with a 41-hour power reserve. It is a movement chosen for its bulletproof reliability, ensuring that while the watch looks like a statement piece, it performs like a professional-grade tool.
Priced at £770, the U1-RIO offers a level of exclusivity and “Made in Italy” craftsmanship that is increasingly rare at this price point. The watch is further elevated by its unique strap options: it ships with two quick-release suede straps, one in the signature verde acqua and another in a striking blush pink.
Both are lined with RIOCAM’s branding and fitted with signed UNIMATIC hardware. This versatility allows the wearer to lean into the tropical aesthetic or dial it back for a more coordinated look. Each caseback is individually numbered and laser-etched with a collaboration graphic, marking its place in this small-batch run.
The UNIMATIC Modello Uno U1-RIO is more than just a diver; it is a celebration of the “golden hour,” a horological tribute to the vibrant, messy, and beautiful intersection of Italian design and Miami soul.
