A tool watch with a sense of style
There is plenty of unobtanium to admire during Geneva Watch Days. You can spend days moving between appointments, marvelling at what happens when watchmakers are given the time, resources, and freedom to pursue something extraordinary. I came home with plenty to think about. Somewhere in among all of that, though, I was equally pleased to put a thoroughly convincing tool watch on my wrist.
UNIMATIC and I have somehow spent the last five years passing like ships in the night. I knew the watches, liked the look of them, and had every reason to sit down with the brand. It finally happened in Geneva. The Modello Quattro UC4 Classic, among others, made the meeting worth the wait.
This is a bruiser of a watch, particularly on a NATO. It makes no apologies for the space it occupies. It also has enough style to make me start mentally sorting through my strap drawer. Those two qualities get along very well here.

An Italian eye for the tool watch
Founded in 2015 by industrial designers Giovanni Moro and Simone Nunziato, UNIMATIC launched with the Modello Uno. The Quattro followed in 2020, introducing the broad, fixed bezel that gives this model so much of its character. The Classic collection became a permanent part of the range in 2021. Together, these watches provide a useful introduction to the Milan-based brand’s design vocabulary.
That industrial-design background helps explain the appeal. Proportions and the spaces between things receive as much attention as the familiar functional details. The Quattro captures that approach particularly well. A substantial steel frame surrounds a restrained dial, giving the whole thing an almost blunt appearance. There is very little visual fuss, yet it is immediately recognisable. Getting that much character out of relatively few elements takes a good eye.
The UC4 Classic is an especially clear expression of the idea. There is room here to appreciate the shape of the watch itself: the width of the bezel, the weight of the lugs, and the relationship between that generous case and the smaller dial opening. Each contributes to its unmistakable silhouette.
A substantial forty millimetres
The brushed 316L stainless steel case measures 40mm across and 49mm from lug to lug. UNIMATIC’s technical sheet lists a thickness of 13.7mm without the crystal and 14mm overall. Those numbers deserve to be read together. Anyone expecting a modest little field watch on the strength of the diameter alone should pay attention to the other two measurements.
The construction includes a fixed monoblock bezel, an 8mm screw-down crown, and a 2.8mm sapphire crystal with internal anti-reflective coating. Water resistance is rated to 300m. Around the back, a compass rose engraving—the Rosa dei venti—provides a decorative flourish appropriate to the watch’s military styling.
I like its heft of appearance. The broad bezel gives the dial a substantial steel frame, while the wide strap keeps everything looking in proportion. Add fabric passing beneath the case on a NATO, and there is considerable watch sitting above your wrist. Its height will be a consideration for some, but the Quattro’s presence is a large part of what draws me to it.
The fixed bezel also helps define its purpose. There is no elapsed-time scale to operate. You get a simple time display within a case whose water resistance makes swimming an entirely reasonable part of its everyday remit.
Black, steel, and pale green
The UC4’s matte black dial carries pale green Super-LumiNova C3, with an off-white closed seconds track and matching printed details. UNIMATIC pairs its ladder-style hour and minute hands with a reverse-lollipop seconds hand tipped in off-white. The display is time only, with no date window to interrupt the arrangement.
There is something appealing about that pale green against the black. It softens the watch’s stern appearance just enough, lending a little colour to an otherwise very restrained palette. The hands’ dark portions blend into the dial, allowing their luminous sections to carry much of the visual weight.
What interests me most is how comfortably all of this sits inside such a muscular case. The dial has breathing room. The bezel supplies the bulk. Together, they give the watch a sense of purpose without filling every available surface with information.

Familiar mechanics
Inside is the automatic NH35A, operating at 21,600 vibrations per hour, hacking seconds, and a stated power reserve exceeding 41 hours. UNIMATIC quotes an accuracy range of −20 to +40 seconds per day without regulation.
It is a familiar movement at this end of the market, and its role here is straightforward. The attraction of the UC4 lies largely in the watch surrounding it. There is also something satisfying about returning to a simple three-hand watch after a week spent contemplating elaborate complications. Set the time, wind it, and get on with the day. I have plenty of room for that kind of watch.
Made for the strap drawer
The UC4 comes on a black heavy-duty nylon NATO with signed, brushed steel hardware. Its drilled 22mm lugs are a welcome detail for anyone inclined to experiment with straps.
The phrase “strap monster” gets thrown around rather freely, but it fits here. There is very little I can imagine putting on this watch that would look out of place. Olive fabric feels like an obvious choice. Leather is especially appealing: its texture and warmth work beautifully with the broad steel bezel. A two-piece strap also removes the layer of fabric beneath the case, bringing the watch closer to the wrist.
After a week of extraordinary watchmaking, this was a welcome reminder of how much enjoyment there is in a well-drawn everyday watch. The Quattro has the bulk and water resistance I appreciate in a tool watch, along with an appearance that keeps me interested long after I have read the time. Five years was a long time to finally meet. I suspect the next conversation will happen rather sooner.
Pricing & Availability
At the time of writing, UNIMATIC’s website displays a price of €550 or C$900. The UC4 belongs to the permanent Classic collection, with individually numbered production in yearly batches. Current packaging includes a black travel pouch and warranty card, and the watch carries a two-year warranty.
