Minimal aesthetics meet serious performance in Unimatic's U1-PD3 ProDiver. Its no-nonsense design incorporates a stainless steel case, which combines with a 2.5mm-thick crystal to enable 300 meters of water resistance. Powered by a dependable Japanese-made NH35A automatic movement, it has dual-color Super-LumiNova on the ceramic bezel insert, geometric markers, and hands, which run over a matte black dial for outstanding legibility in low light. Limited to 300 examples, it arrives in a Unimatic tough case on a heavy-duty black nylon NATO strap.
