Comparing The New Titanium Unimatic Modello Quattro UT4-U-TI-GMT To The Stainless Steel UT4-GMT

Almost two years ago, Unimatic surprised us with its Toolwatch series, consisting of four stainless steel quartz models added to the Italian brand’s permanent lineup. Two of them are variants of the Modello Uno, while the other two are Modello Quattro models. Back then, I had a chance to try out the Modello Quattro UT4-GMT, based on Unimatic’s modern take on a field watch with an added GMT function. Now, almost two years later, the brand has released two titanium versions of the Modello Quattro watches. I had a chance to compare the new UT4-U-TI-GMT to its stainless steel counterpart. As it turns out, there is more to the story than just a change in materials.

Just a quick reminder: the Unimatic Toolwatch series is built around a shock-protected construction with military-grade specs. On top of that, the four watches presented a look that Unimatic had only used in 2023 for the Modello Quattro UT4-B. It’s a more standard dial design with regular Arabic numerals rather than the brand’s signature minimalist aesthetic. But one quick look at the new Modello Quattro UT4-U-TI-GMT told me that a different case material wasn’t the end of the story. The updated dial design creates a slightly different look and feel. I didn’t have an immediate opinion, so I decided to compare the new titanium version with the stainless steel model.

The details of the Unimatic Modello Quattro UT4-U-TI-GMT

Before we get into the intricacies of the dial design, let’s first talk specs. The new Modello Quattro UT4-U-TI-GMT has a 40mm sandblasted Grade 2 with a 49mm lug-to-lug and 12mm profile. This case has the same dimensions as the stainless steel model. The main difference, of course, is the lower weight, which makes the watch easier to wear. Additionally, the sandblasted titanium is slightly darker than its stainless steel counterpart. Otherwise, the case features the same design, with its signature flat bezel giving it a distinct, modern look.

As I explained in the introduction article to the Toolwatch series, the watches were developed in accordance with the U.S. MIL-STD-810 testing standard. To ensure the watches withstand rigorous testing, Unimatic equips them with its signature 360° anti-shock system. It protects the quartz movement, resulting in a rugged daily wearer that can withstand pretty much everything you throw at it. But whereas the first four models proudly featured the “MIL-STD-810” text on the lower half of the dial, the new watch doesn’t. It doesn’t mean that this new model is less rugged, but Unimatic didn’t necessarily test it to the same standard.

The new dial design of the Unimatic Modello Quattro UT4-U-TI-GMT

Inside the case sits a matte black dial in the same style as its steel predecessor. It features an open minute track with Arabic numerals set inside. There is also a date window at 6 o’clock and an extra aperture at 12 to display the current hour in another time zone. So far, there’s nothing too different here. However, as you can see, the Arabic numerals on the new dial are significantly larger, making it easier to read the time. It fits the watch’s utilitarian nature.

While I prefer a more refined approach to design, the new aesthetic needs context. If you were to wear this watch out and about, you would want to be able to read the time immediately. This watch offers uncompromised legibility in that regard, while the more refined looks of the steel model at least needed some focus. However, as a result of the larger numerals, the display for the second time zone is very close to the numerals at 12 o’clock. This doesn’t necessarily hurt the readability, but I like it when a design has room to breathe. Going back to prioritizing reading the time instantly, though, this is an easy compromise to accept.

The orange details are slightly different

Another visual difference is the absence of the orange “MIL-STD-810” text on the lower half of the dial. As mentioned, the stainless steel series was tested according to that specific standard, whereas the two new titanium models weren’t. Consequently, the new dial doesn’t have that colorful orange fourth line of text on the lower half. Considering the larger numerals on the dial, the space between them and the text creates a nice bit of breathing room.

Little hints of color come in the form of the triangular orange indicator for the second time zone, the orange tip of the seconds hand, and the orange ring on the rehaut, which is part of the shock-protection system. The numerals and hands light up blue in the dark with white Super-LumiNova GL C1. As you will understand, the larger luminous numerals have also made this easier.

The Ronda 515.24D quartz caliber

Powering the watch is the same Swiss Ronda 515.24D movement that also powers the stainless steel model. It has an accuracy of +20/-1 seconds per month and a 45-month battery life. The movement is safely hidden behind a steel screw-in Ultratool case back. This has a different design than the Unimatic 360° X-ray case back used for the stainless steel version.

Wearing the Unimatic Modello Quattro UT4-U-TI-GMT

Finishing the look of the new Unimatic Modello Quattro UT4-U-TI-GMT is a black and International Orange three-layer nylon strap with a titanium buckle. The combination of black and orange works well and adds a nice visual sparkle to the watch compared to the stainless steel version’s all-black nylon strap. Once you put the new Modello Quattro on your wrist, its low weight becomes immediately apparent. I am used to the hefty and sturdy steel Unimatic watches, so this new titanium one feels like a breath of fresh air.

What remains is the solid feel that reassures you that this watch can take a beating. On top of that, the 22mm nylon strap is comfortable but also feels super sturdy. As always, Unimatic didn’t cut any corners, ensuring this is a proper tool watch that should perform as one in any given situation. With the updated dial design, Unimatic made sure it could do so even better than the previously introduced model. In that context, I can only compliment the brand’s founders, Giovanni Moro and Simone Nunziato, for ensuring that form follows function.

My impressions of the Unimatic Modello Quattro UT4-U-TI-GMT

While I initially preferred the design of the previous models because they are slightly more refined, I also had to remind myself of the purpose of these watches. And as a rugged tool watch, the new titanium version is objectively better. It is easier to wear and read thanks to the lightweight titanium case and the larger numerals on the dial. On top of that, operating the different functions remained just as easy as before.

While the titanium crown isn’t as buttery smooth as the stainless steel one, it unscrews easily. Pulling it to the first position lets you adjust the date and time in the second time zone. What has stayed is that the date advances one click at a time, and the 24-hour GMT disc scrolls forward smoothly. As a result, you have to position it as close as possible to the centrally displayed time. Therefore, it is best to set it to the exact hour to ensure the time is displayed correctly. The advantage is that it also lets you display the time in all 40 time zones, including those with 30- or 45-minute offsets.

A clever update that puts function first

After wearing the two watches for several days, I can say I prefer the new titanium UT4-U-TI-GMT to the stainless steel UT4-GMT. The lightweight titanium case and the optimized functionality make it a better tool watch, which is what Unimatic set out to do with this new release. At €730, the Modello Quattro UT4-U-TI-GMT is a very affordable, competent, and cleverly updated offering.

Consequently, I don’t doubt that all 99 pieces that are available on the official Unimatic website will sell out quickly. The same goes for the Modello Quattro UT4-U-TI, which is essentially the same watch without the GMT function. If you don’t care about a second time zone, it is an even more affordable option at €610. Unimatic will also produce 99 pieces of this version. Overall, this is a nice update. While it isn’t as stylish or daring as some of the other limited editions, it does exactly what it promises, and therefore, it is right on the money.
