This is the new Unimatic Modello Uno U1-GMT-AEG, it’s one of the latest limited edition releases from the highly-regarded watchmaker, each is made in Italy, and they’re powered by an automatic movement.
If you look closely you’ll notice that the watch has four hands rather than the usual three. That fourth hand tracks a second timezone around the bezel which is marked out with a military-style 24-hour clock. This allows you to see the time in two parts of the world on one watch face at a glance.

History Speedrun: Unimatic Watches
Unimatic was founded in Milan in 2015 by Giovanni Moro and Simone Nunziato, two industrial designers who met while studying at Politecnico di Milano. Moro had designed a watch for fun while working at a furniture company, but he felt it wasn’t quite right. When he tried again, he reached out to Nunziato, and the pair set out to build the watch they’d always had in mind – without a business plan.
Their first release, the Modello Uno, was a minimalist dive watch inspired by classic dive watches of the 1950s, with a 40mm stainless steel case and a Seiko NH35A automatic movement. Its limited production run sold out quickly, this largely established the DNA of the company. The brand name itself is a portmanteau of the Latin words “unico” (unique) and “matic” (willing or able).
A core part of Unimatic’s business model has always been a balance between exclusivity and scarcity. The company typically releases new watch designs in limited number batches, and once they sell out, that design is retired, never to be used again.
In more recent years they introduced their first ever permanent collection, the Unimatic Classic series, which remains continuously available, but the bread and butter of their business remains the limited edition designs.
The Unimatic watch lineup has expanded considerably from that original Modello Uno diver. Models now include the Modello Due field watch, the Modello Tre chronograph, and the Modello Quattro military watch, all keeping the brand’s signature minimalist design.
If you look closely you’ll notice that the watch has four hands rather than the usual three. That fourth hand tracks a second timezone around the bezel which is marked out with a military-style 24-hour clock. This allows you to see the time in two parts of the world on one watch face at a glance.
In 2025, Unimatic launched the ProDiver collection with 600 meters of water resistance and pairing it with the highly-regarded Sellita SW200-1 automatic mechanical movement from Switzerland.
The Unimatic Modello Uno U1-GMT-AEG
Unimatic’s new Impronte Collection is a 10-piece run of limited edition watches including the Modello Uno, Tre, and Quattro platforms – the U1-GMT-AEG is arguably the standout model of the group.
The name of the collection means “imprints” in Italian, and the theme incudes raised bezel numerals, debossed dial details, and a textured “wrinkled” caseback. Unimarix explains that the idea is for the surfaces reveal themselves through light, shadow, and touch rather than by using color alone.
The U1-GMT-AEG is built around the familiar Modello Uno diver case, it’s 40mm across, 41.5mm at the bezel, 49mm lug-to-lug, and 14.4mm thick including the double-domed sapphire. It’s made from brushed 316L steel, rated to 300 meters of water resistance, with Unimatic’s 8mm Alchemical Sun screw-down crown.
The AEG version pairs an aluminum-tone dial and hands with a sandblasted aluminum 24-hour bezel insert, with Super-LumiNova C1 lume, and a hollow-arrow GMT hand tracks the second time zone.
Each is individually numbered from an edition of 250, it ships with olive drab and black seatbelt NATO straps in a tough polycarbonate case.
The watch is powered by the Seiko NH34A automatic, this is a caller-style GMT running at 21,600 bph with hacking seconds, hand winding, and a 41 hour power reserve.
Each is individually numbered from an edition of 250, it ships with olive drab and black seatbelt NATO straps in a tough polycarbonate case, and it’s priced at $1,050 USD delivered to the US. You can visit the official Unimatic store here if you’d like to read more.
