ProTek PT4001 Aggressor Watch

Wristwatch with an analog dial encased in a lightweight yet durable watchcase. The design is water-resistant to 30 atmospheres (300 m), allowing for safe use of the device while diving.

The model is equipped with a Japanese Citizen (Miyota) 2035 quartz movement, which ensures stable operation, good time measurement accuracy, and low energy consumption, resulting in a long operation period (up to 4 years) on a single battery.

The watch mechanism is housed in a black watchcase with a diameter of 45 mm made from lightweight carbon composite, known for its high damage resistance while maintaining low weight. The screwed crown is made from 316L stainless steel and features a multi-seal ring system, and a steel caseback ensures high construction tightness. The setup achieves a water resistance of 300 meters (30 ATM), enabling safe watch use while diving.

The model is equipped with a unidirectional rotating bezel with a 60-click mechanism, allowing for precise time measurement, also during diving. The bezel features clear minute markings (every 10 units). The black dial is protected by high-quality sapphire crystal with an anti-reflective coating, which reduces light reflections and enhances readability in various lighting conditions.

At the 12 o’clock position, there is a highlighted marker encompassing both the dial index and the orientation point on the diving bezel. This solution facilitates quick reference time setting and enhances readability, especially in low visibility conditions.

The watch is fitted with a screwed caseback made from high-quality 316L stainless steel, providing high construction tightness and resistance to moisture and external factors. The surface of the caseback is adorned with geometric, precise embossing with distinct, deep edges that emphasize the character of the model.

Timekeeping is managed by the Japanese quartz Citizen (Miyota) 2035 movement with three hands. It is designed to offer stable operational parameters, ensuring consistency in indications and good accuracy in time measurement. The mechanism features low power consumption, allowing operation on a single battery for up to approximately 4 years.

The watch uses a Swiss tritium illumination system Pro-Glo T100 providing constant visibility of the indications for up to 25 years without needing recharging by external light. The light source is hermetically sealed micro tubes filled with tritium, which emit even, continuous light regardless of the surrounding conditions.

The system does not require pre-illumination, maintaining full functionality both in complete darkness and underwater. The high brightness intensity facilitates quick reading of indications, which is crucial during diving, night operations, and working in limited visibility.

The model is equipped with a black rubber strap with a width of 22 mm, finished with a steel buckle. The strap adapts well to the wrist, providing high wearing comfort and effectively preventing the watch from shifting.
