Model PT4001 Aggressor
Description
The ProTek Model PT4001 Aggressor is a serious 45mm carbon composite dive watch engineered for divers, adventurers, and tactical professionals who demand reliability in extreme conditions. Built with 300-meter water resistance and a 60-click unidirectional ratcheting dive timing bezel, this watch is purpose-built for underwater performance and everyday rugged use. Every watch is individually tested in both air and water before it leaves the factory, so you can trust it from the moment it's on your wrist.
What truly sets the Aggressor apart is its Swiss self-powered Pro-Glo T100 tritium illumination system, which glows continuously for 25 years - no charging required, and 100 times brighter than conventional photoluminescent lume. Paired with a sapphire crystal featuring anti-reflective coating and a dependable Miyota 2035 quartz movement with a 4-year battery, this is a dive watch that just works, day or night, dive or dry land.

FAQ
What is tritium illumination and how is it different from standard lume?
Tritium is a self-powered, radioactive hydrogen isotope sealed inside tiny glass tubes on the watch hands and indices. Unlike standard photoluminescent lume - which must be "charged" by exposure to light and fades within hours - tritium glows continuously on its own for up to 25 years. The Pro-Glo T100 system on the Aggressor is 100 times brighter than conventional lume and works equally well in complete darkness, making it a favorite among divers, military personnel, and tactical users.
Is the Aggressor suitable for recreational scuba diving?
Absolutely. With 300-meter water resistance, a unidirectional dive timing bezel, and T100 tritium illumination, the PT4001 Aggressor meets and exceeds the functional requirements for recreational scuba diving. Every watch is individually pressure-tested in both air and water before it ships, so you can trust the rating completely.
Can I swap the strap on the Aggressor?
Yes - the Aggressor uses standard quick-release spring pins with a 22mm lug width, making strap changes easy and tool-free. ProTek also sells additional straps in Blue, Yellow, and Orange separately, so you can customize the look to match your style or activity.
How long will the battery last, and can it be replaced?
The Miyota 2035 quartz movement is rated for a 4-year battery life under normal use. When it's time for a replacement, any watch repair shop or jeweler can swap the battery. Just be sure to have a professional re-seal the crown and caseback afterward to maintain water resistance.
What is the difference between the PT4001, PT4003, PT4004, and PT4007 Aggressor models?
All four Aggressor models share the same core specifications - 45mm carbon composite case, 300-meter water resistance, T100 tritium illumination, and Miyota quartz movement. The differences between model numbers typically relate to dial color and crown/strap color combinations.
