Brand History
Unimatic
Unimatic, founded in 2015 by Giovanni Moro and Simone Nunziato, operates as a continuous watchmaking research lab offering unique, Italian-made watches that blend excellent design, iconic elements, and cutting-edge technical solutions. Their first product, the Modello Uno, was followed by a field watch and a chrono-diver, all water-resistant to 300 meters. Each watch is individually engraved with a serial number and total production quantity, ensuring uniqueness.
