ProTek PT4003 – 4000 Series Carbon Composite Aggressor, Light Blue Dive Watch

Built for adventurers, divers, and tactical users who demand rugged performance and clarity in all conditions, the ProTek PT4003 Aggressor combines professional-grade features with all-terrain versatility.

The PT4003 introduces light blue accents that add contrast and visual clarity to ProTek’s most aggressive dive watch platform. Featuring a rugged 45 mm carbon composite case, 60-click unidirectional ratcheting dive bezel, light blue dial details, and a matching light blue rubber strap, this model balances bold style with serious dive-ready performance.

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 PT4003 is water-resistant to 300 meters, with each watch individually tested in both air and water for true dive capability.

Designed for maximum readability in low-light environments, the PT4003 is equipped with Swiss self-powered ProGlo™ T100 tritium illumination, which glows continuously for up to 25 years without requiring any external charging.

The dial is paired with a durable 22 mm rubber strap, secured by a reinforced steel signature buckle and quick-release spring pins for easy strap changes. Optional color-matched straps are available separately for those who want to further personalize their setup.
