The ProTek Aggressor PT4003 is built for durability and visibility, featuring a 45 mm carbon-composite case that delivers strength while remaining lightweight and comfortable for extended wear. Its corrosion-resistant construction makes it well-suited for demanding dive environments.

Powered by a reliable Japanese quartz movement, the watch offers dependable performance and precision timekeeping. The dial is protected by an anti-reflective sapphire crystal and features color-coded, self-powered luminous hands and markers that provide constant illumination for up to 25 years—even in complete darkness.

Designed with both function and style in mind, the watch includes a genuine rubber strap and is available with textured dials and matching crowns in four bold color options.
