ProTek PT4001 Aggressor Watch

Wristwatch with an analog dial placed in a lightweight yet durable case. The design is prepared for use in water conditions, which makes the model suitable for diving. Water resistance at a level of 30 atmospheres (300 m) allows for safe use underwater, even at greater depths.

It uses a Japanese quartz movement Citizen (Miyota) 2035, which ensures operational stability, high time measurement accuracy, and low energy consumption, resulting in a long working time (up to 4 years) on one battery.

The watch's movement is housed in a black case with a diameter of 45 mm made of lightweight carbon composite, characterized by high strength while maintaining low mass. A screw-in crown made of 316L stainless steel and a multi-ring gasket system, along with a steel caseback, guarantee a high degree of sealability of the construction. The entire assembly achieves water resistance at a level of 300 meters (30 ATM), allowing for safe use while diving.

The model is equipped with a unidirectional rotating ring with a 60-click mechanism, enabling precise time measurement underwater. The ring features minute markings every 10 units. The dial is protected by sapphire glass with an anti-reflective coating, which reduces light reflections and enhances readability under various lighting conditions.

At the 12 o'clock position, there is a distinguished marker, encompassing both an index on the dial and a reference point on the diving ring. This arrangement allows for quick reference time setting and improves readability, especially in limited visibility.

Watch with a screw-in caseback made from durable 316L stainless steel, resulting in high construction sealability and resistance to moisture and external factors. The caseback's surface is adorned with a geometric, precisely embossed pattern featuring clear, deep edges that emphasize the model's character.

Time measurement is ensured by a Japanese quartz Citizen (Miyota) 2035 movement with three hands. It has been designed for stable operating parameters, providing consistent readings and good time measurement accuracy. The movement is characterized by low energy consumption, enabling long operation on a single battery - up to approximately 4 years.

The Swiss tritium illumination system Pro-Glo T100 is used, guaranteeing constant visibility of indications for up to 25 years without the need for external light recharging. The light source consists of sealed micro-tubes filled with tritium, emitting even, continuous light regardless of environmental conditions.

The system does not require prior exposure to light, maintaining full functionality both in total darkness and underwater. The high luminosity facilitates quick reading of indications, which is particularly important during diving, night operations, and working in limited visibility conditions.

Model with a black rubber strap with a width of 22 mm, finished with a steel buckle. The strap fits well on the wrist, ensuring high wearing comfort and effectively preventing the watch from shifting.
