Model PT4003 Aggressor


Description

The ProTek Model PT4003 Aggressor is a serious 45mm carbon composite dive watch built for those who demand reliability under pressure. With 300-meter water resistance - individually tested in both air and water - this watch is ready for open-water dives, tactical use, or any adventure that calls for uncompromising performance. The 60-click unidirectional ratcheting bezel, sapphire crystal with antireflective coating, and screw-in crown with multiple O-rings reflect a level of engineering that serious divers and outdoor enthusiasts will immediately appreciate.

What truly sets the PT4003 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 standard photoluminescent lume. Paired with a dependable Japanese Miyota 2035 quartz movement and a genuine rubber strap with quick-release spring pins, the Aggressor is a watch you can trust the moment you strap it on.

FAQ

What is tritium illumination and how does it work?

Tritium is a radioactive isotope of hydrogen that emits a low-level glow when it interacts with a phosphor coating inside sealed glass tubes. Unlike traditional photoluminescent lume, tritium does not need to be "charged" by a light source - it glows continuously on its own. The Pro-Glo T100 system used in the PT4003 is rated for 25 years of continuous illumination and is 100 times brighter than standard lume, making it an outstanding choice for divers and anyone who needs reliable low-light readability.

Can I swap the rubber strap for a different one?

Yes. The PT4003 features easy on/off quick-release spring pins on its 22mm lug width, so you can swap straps in seconds without any tools. Blue, Yellow, and Orange straps are sold separately, giving you the flexibility to customize the look of your watch.

How deep can I dive with the PT4003 Aggressor?

The PT4003 is water resistant to 300 meters, which exceeds the requirements for recreational scuba diving (typically rated to 40 meters) and is well into the range for technical and professional diving applications. Every watch is individually tested in both air and water before leaving the factory.

What does "unidirectional" mean for the dive bezel?

A unidirectional bezel can only rotate in one direction - counterclockwise. This is a critical safety feature for dive timing: if the bezel is accidentally bumped during a dive, it will only move in the direction that reduces your indicated bottom time, never extending it. This prevents you from accidentally thinking you have more time underwater than you actually do.

How often does the battery need to be replaced?

The Miyota 2035 quartz movement in the PT4003 is rated for approximately 4 years of battery life. When it is time for a replacement, any qualified watchmaker or jewelry shop that services watches can replace the battery. Be sure to have the water-resistant seals inspected and replaced at the same time to maintain the watch's 300-meter water resistance rating.
