Unimatic U3-DHB | Diving Heritage Collection

This stealthy chronograph diver from Unimatic is part of their limited Diving Heritage collection, with only 300 pieces made worldwide. 

The Modello Tre U3-DHB is a robust chrono-diver with a purposeful matte black dial and bezel, complemented by creamy Super-LumiNova® GL Light Old Radium markers for a vintage touch. Its mono-eyed chronograph layout adds unique character, while the matte black aluminium bezel insert with matching raised lume dot reinforces its rugged tool watch identity. Built for timing everything from laps to dives, the U3-DHB combines precise functionality with Italian-made craftsmanship.

At 40mm with a 41.5mm unidirectional bezel and meca-quartz reliability, this watch offers the perfect balance of vintage style and modern performance.
