Protek PT4001 – 4000 Series Carbon Composite Aggressor, All-Black Dive Watch

Built for adventurers, divers, and tactical users who demand rugged performance and clarity in all conditions, the ProTek PT4001 Aggressor combines professional-grade features with all-terrain versatility.

Ideal for professionals who prefer a low-visibility, no-nonsense aesthetic, the PT4001 Aggressor delivers uncompromising dive performance in a fully blacked-out configuration. Featuring a rugged 45 mm carbon composite case, 60-click unidirectional ratcheting dive bezel, black dial, and black rubber strap, this model embodies a stealth-first approach to ProTek’s most aggressive dive watch platform.

At its heart is a dependable Japanese Citizen/Miyota 2035 quartz movement with a long-lasting 4-year battery, ensuring reliable timekeeping wherever life takes you. The PT4001 is water-resistant to 300 meters, with each watch individually tested in both air and water for true dive capability.

Despite its all-black appearance, legibility is never compromised. ProTek’s Swiss self-powered ProGlo™ T100 tritium illumination provides continuous glow for up to 25 years, delivering instant readability in total darkness without requiring external charging.

The dial is paired with a genuine rubber strap (22 mm), secured by a reinforced steel signature buckle with quick-release spring pins for easy strap changes. Color-matched strap options (such as blue, yellow, and orange) are available separately to customize your look.
