Unimatic Modello Uno U1-DN

The 40 mm steel case, 41.5 mm across the bezel, is brushed and then coated in black DLC, and the hardware on both supplied straps, a nylon NATO and a black rubber diving strap, is DLC to match. The date disc matches the dial, so the window at 6 keeps to the same colour. White Super-LumiNova C1 on the markers and phantom ladder hands matches the lume pearl on the aluminium bezel insert. It is rated to 300 m, takes a 22 mm strap and runs on the Seiko NH35A automatic, with hacking seconds and a 41-hour power reserve.

The U1-DN keeps the black dial and dive bezel of the U1-A (also 300 pieces), U1-D and U1-E, but its case is coated black, where the U1-A's steel alternates polished and brushed surfaces. The U1-DL is the blue-dial Luisaviaroma edition of the same layout, in 50 pieces.
