The Pro-Tek PT4001 is a rugged dive watch designed for demanding outdoor and water-based environments, combining a lightweight 45mm carbon composite case with professional-grade dive-oriented features. Its 60-click unidirectional ratcheting dive timing bezel provides a reliable way to track elapsed time underwater, while the 300-meter water-resistance rating makes the PT4001 well suited for serious aquatic use.

A 316L stainless steel screw-in caseback and matching 316L stainless steel screw-in crown with multiple O-rings provide a durable, secure construction. The crown color is matched to the watch dial for a distinctive finished appearance. A sapphire crystal with antireflective coating helps resist scratches while reducing glare for improved readability.

The PT4001 is powered by a dependable Japanese Citizen/Miyota 2035 quartz 3-hand movement with an approximately four-year battery life. Each watch is tested in both air and water to verify its 300-meter water-resistance rating.

For low-light visibility, the PT4001 features the Swiss self-powered Pro-Glo T100 illumination system. The system requires no external light source for charging and is designed to provide continuous illumination for up to 25 years. Pro-Glo T100 illumination is designed to provide substantially greater brightness than conventional photoluminescent lume systems.

The watch is fitted with a genuine rubber strap measuring 22mm x 20mm and a steel signature buckle with easy on/off quick-release spring pins. Additional blue, yellow, and orange straps are available separately, allowing the watch to be customized to suit individual preferences.

At 82 grams with 22mm lugs, the PT4001 balances a substantial 45mm case with lightweight carbon composite construction for a capable dive and adventure watch.
