UNIMATIC has rapidly carved out a distinct niche in the world of timekeeping, celebrated for its minimalist, utilitarian design language that strips dive watches down to their essential, functional forms while maintaining a compelling aesthetic. Their creations are built with a singular focus on robustness and clarity, and the Black Diver Modello Uno U1S-MD watch is a prime example, presented as a piece explicitly engineered for the depths with an impressive 300-meter water resistance rating and a striking, stealthy appearance.
This is a Slim Professional Diver from the Modello Uno lineage (ref. U1S-MD), immediately distinguished by its full black DLC brushed finish applied seamlessly across both the stainless steel case and bracelet. This provides a cohesive, stealth aesthetic that is both visually arresting and highly functional, reducing glare in challenging conditions. Assembled with precision and carrying the desirable “Made in Italy” designation, it blends robust engineering with a refined, minimalist design sensibility.
The case measures a versatile 40mm in diameter (41.5mm including the bezel) with a substantial 49mm lug-to-lug height and a slim 11.6mm thickness, crafted from solid 316L brushed stainless steel. The case is designed for true underwater capability, featuring an 8mm diameter Alchemical Sun screw-down crown and a screwed-in 2 mm thick caseback, all secured with high-quality gaskets to provide that formidable 300m water resistance – individually tested to 30atm, confirming its readiness for serious diving depths.
The dial is a study in legible minimalism designed for the darkest conditions. It features a matte black ceramic diving insert with Super-LumiNova® BGW09 markers on a precise 120 clicks mono-directional safety bezel. The matte black diver dial itself is infused with dual Super-LumiNova® BGW09 and vibrant OL orange accents, ensuring top-tier visibility. Time is displayed via a matte black ladder hands set, with a reverse lollipop design for the seconds hand.
Lume application is deliberate: Super-LumiNova® BGW09 on the minute hand, and Super-LumiNova® white custom emission with OL orange on the hour and seconds hands, providing crucial contrast for timing underwater. A matte white closed second rail and dial trims add subtle definition. The double-domed 2.5mm thick sapphire crystal, with inner side anti-reflective coating, ensures both extreme durability and optimal performance in every light condition.
Powering this robust tool watch is the Swiss automatic Sellita SW200-1 b calibre. This is a reliable self-winding/manual winding movement operating at a smooth 28,800 vibrations per hour (4 Hz), offering 38 hours of power reserve and featuring a hacking second hand for precise time setting. Each watch is singularly tested for accuracy, underscoring the commitment to performance.
The watch comes on a black DLC brushed finish solid steel bracelet, signed UNIMATIC, maintaining the cohesive stealth look. The caseback features the distinctive UNIMATIC conversion scale engraving and the individual progressive number, highlighting its limited status.
The UNIMATIC Black Diver Modello Uno U1S-MD is a unique edition, strictly limited to just 99 pieces worldwide, individually numbered on the caseback. It comes in a UNIMATIC tough case with a warranty card and unique ID seal, covered by a 24-month worldwide warranty.
Available at a price point of £1350, this watch is a formidable limited-edition professional diver from UNIMATIC, distinguished by its full black DLC stealth aesthetic, robust build (300m WR, quality materials), meticulous dial/lume details, and a reliable Swiss automatic movement. It stands as a seriously capable and highly collectable tool watch for the depths, executed with UNIMATIC’s signature minimalist Italian design sensibility.
