ProTek PT4004 Aggressor Watch

Wristwatch with an analogue dial housed in a lightweight yet durable case. The design is prepared for use in water conditions, making the model suitable for diving. Waterproofing at a 30 atmosphere (300 m) level allows for safe underwater use, even at greater depths.

Additional options such as a stopwatch and Pro-Glo T100 illumination expand the watch's applications. It features a Japanese Citizen (Miyota) 2035 quartz movement, ensuring operational stability, high time measurement accuracy, and low energy consumption, resulting in a long working time (up to 4 years) on a single battery.

The watch mechanism is housed in a black case with a diameter of 45 mm made of lightweight carbon composite, characterised by high strength while maintaining low weight. The screw-down crown made of 316L stainless steel and a multi-ring gasket system, as well as a steel caseback, ensure a high level of seal integrity. The whole unit achieves waterproofness at a 300 meter (30 ATM) level, allowing for safe use of the watch during diving.

Model equipped with a unidirectional rotating bezel featuring a 60-click mechanism, allowing for precise time measurement underwater. Minute markings are indicated on the bezel every 10 units. The dial is protected by sapphire glass with an anti-reflective coating, reducing light reflections and enhancing legibility in various lighting conditions.

At 12 o'clock, a distinctive marker is applied, covering both the dial index and the reference point on the diving bezel. This solution enables quick reference time setting and improves legibility of readings, especially in limited visibility.

The watch features a screw-down caseback made from durable 316L stainless steel, resulting in high construction tightness and resistance to moisture and external factors. The caseback surface is adorned with geometric, precise embossing with distinct, deep edges, which highlight the character of the model.

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

The Swiss tritium illumination system Pro-Glo T100 is used, guaranteeing constant readability of indications for up to 25 years without requiring external light charging. The light source consists of tightly sealed microtubes filled with tritium, emitting uniform, continuous light regardless of the surrounding environment.

The system does not require prior exposure to light, maintaining full functionality both in complete darkness and underwater. High luminous intensity facilitates quick reading of indications, which is of particular importance when diving, conducting night operations, and working in conditions of limited visibility.

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