This is the Modello Uno U1S-PD6-RB ProDiver, it’s a limited edition watch from the wildly popular microbrand, and each one is made in Italy with a Swiss automatic movement.
The Unimatic ProDiver series is water resistant to 600 meters, that’s 2,000 ft or 60 ATM, making it more than capable as a reliable dive watch capable of much greater depths than any human. The deepest a person has ever dived is 332 meters, or 1090 ft, a record set in 2014 by Ahmed Gabr.

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.
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 ProDiver is rated to a depth of 600 meters (2,000 ft or 60 ATM), making it highly capable as a genuine tool watch for divers.
