Restraint is the most underrated discipline in design, especially with watches.

For decades, Rolex has barely touched the Submariner, Oyster Perpetual and other key models. Seiko continues to rely on its design language from the 1960s. And Timex has built its comeback on replicating archival watches.

A Unimatic wristwatch with a black dial and white hour markers, featuring a date window at the 6 o'clock position. The watch has a matte silver bezel with minute markings and a black nylon strap with silver hardware. The dial includes the text "UNIMATIC," "MADE IN ITALY," and "600m=2000ft." The watch hands are white with a bold design, and the second hand has a circular tip. — The titanium U1S-T-PD6-B is the first Unimatic dive watch with 600m water resistance.

No young watch brand understands the virtue of design discipline — knowing when the work is finished, and not fixing what isn’t broken — better than Unimatic.

The Italian watchmaker was founded in 2015 by former industrial designers Giovanni Moro and Simone Nunziato. From the beginning, a distinct design ethos was established, and adhering to it has helped elevate the brand above most of its microbrand peers.

Three wristwatches with black straps are displayed on a dark surface. The left watch has a black dial labeled "U1S PD3-B," the middle watch has a dark blue dial labeled "U1S-T PD6-B," and the right watch has an orange dial labeled "U1S PD3-OR." Each watch features a rotating bezel with minute markers and luminous hour markers on the dial. — The Unimatic ProDiver series retains the brand’s signature look.

After ten years of escalating success in the industry, Unimatic remained committed to its trademark aesthetic when designing its most ambitious set of dive watches.

The new additions to the ProDiver series, which debuted in 2023, consist of three watches. One boasts a 600m water resistance, the highest that Unimatic has ever achieved. The other two references offer more modest performance at an affordable price for the flagship Modelo Uno.

The watch has a black rotating bezel with white minute markings and a stainless steel case. It is paired with a black fabric strap with a black buckle. The dial includes the text "UNIMATIC MADE IN ITALY AUTOMATIC 300m/1000ft. — The steel U1-PD3 comes with an orange dial or black dial, and has 300m water resistance.

All three dive watches blend seamlessly into the Modelo Uno collection with Unimatic’s distinctive minimalist geometric dial, bold bezel frame and substantial crown guard.

A titan of the deep

The ProDiver Modelo Uno U1S-T-PD6-B is the most impressive dive watch Unimatic has ever created, capable of descending to a depth of 600m, 100m more than any previous reference.

The watch has a black fabric strap with metal loops and a date window at the 6 o'clock position. The watch case is metallic with a textured crown on the right side. The dial indicates "UNIMATIC," "MADE IN ITALY," and "600m=2000ft. — The U1S-T-PD6-B has a sandblasted finish on the titanium case and bezel frame.

Its sandblasted 41.5mm titanium case measures 12.3mm in height, one millimeter less than the steel ProDiver references despite having double the water resistance. This includes the protruding 3mm thick double-domed sapphire crystal with inner anti-reflective coating.

The coin-edge sandblasted titanium bezel, with 120-click unidirectional turning, holds a ceramic insert with a 60-minute dive scale made with infused Super-LumiNova.

The minute hand and dive bezel lume glow blue to assist with timing descents. Orange lume differentiates the hour hand, the seconds hand and the hour markers.

The watch face includes the text "UNIMATIC," "MADE IN ITALY," and "600ft/200m." The bezel has minute markers in blue, and the watch is set against a blue background. — The dial and bezel features Super-LumiNova BGW09 markers.

The U1S-T-PD6-B also mechanically outperforms its fellow ProDivers. It runs on the same Sellita caliber SW200-1a automatic movement that powered the original ProDiver and many other Unimatic watches.

While the SW200-1a matches the 41-hour power reserve of the Seiko caliber NH35A used in the other two references, it has a higher frequency at 28,800 beats per hour and two additional jewels, resulting in more consistent accuracy.

A flagship refitted

The two U1-PD3 references offer more affordable entry points to Unimatic’s ProDiver series. To preserve the 300m diving integrity of the original ProDiver, Unimatic swapped in the more affordable Seiko caliber NH35A automatic movement.

Both U1-PD3 references come on all-black nylon NATO straps with steel hardware.

While still a respectable movement, it has a lower frequency of 21,600 beats per hour and a measured accuracy of -20/+40 seconds per day, compared to the Sellita SW200-1a’s +/-12 seconds per day. It also forced Unimatic to expand the case thickness to 13.2mm to accommodate the larger movement.

The tradeoff is a much more affordable price of €750 (~$877), a fair price for an automatic dive watch with 300m water from a well-respected brand.

The U1-PD3 has a brushed steel case and bezel, featuring an identical ceramic bezel insert to the titanium model. It also has the same dial lume and a 3mm thick double-domed sapphire crystal.

The only difference between the two U1-PD3 references is a black or orange dial.

The watch has a stainless steel case, a black rotating bezel with white minute markings, and a black fabric strap. The hands are thick and white, with the hour hand being shorter and the minute hand longer. The text "UNIMATIC MADE IN ITALY 300m=1000ft" is visible on the dial. — The U1-PD3 also comes with a black dial.

Unimatic has always led with design, but with Italy’s rich history of aquatic timekeeping, it is a point of pride to be counted among the country’s best dive watch manufacturers.

The ProDiver series strays from Unimatic’s devout minimalism just enough to function as a premier diver. Fans can now get the brand’s signature look with top-shelf performance, or affordable alternatives with more-than-adequate specs.
