ProTek PT4105SFC USMC Carbon Dive Watch

Wristwatch with an analog dial enclosed 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, ensuring stable operation, good timekeeping accuracy, and low energy consumption, resulting in a long operational period (up to 4 years) on a single battery.

The watch mechanism is enclosed in a 45 mm diameter case made of lightweight carbon composite, known for its high damage resistance while maintaining low weight. A screw-down crown made from 316L stainless steel, equipped with a multi-ring sealing system, as well as a steel caseback ensure high sealing of the structure. The entirety achieves water resistance of 300 meters (30 ATM), allowing for safe use of the watch 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 Green Camo 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, a distinguished marker is applied, including both the index on the dial and the reference point on the diving bezel. This solution facilitates quick setting of the reference time and improves the readability of the indications, especially in limited visibility conditions.

The watch features a screw-down caseback made of high-quality 316L stainless steel, contributing to the high sealing of the structure. Its surface is adorned with the embossed emblem of the United States Marine Corps (USMC) along with the inscription "The Proud 250 Years of Uncommon Valor," referring to the formation's jubilee.

The timekeeping is managed by the Japanese Citizen (Miyota) 2035 quartz movement with three hands. It is designed with stable performance parameters, resulting in repeatable indications and good timekeeping accuracy. The movement is characterized by low energy consumption, allowing for long-lasting operation on a single battery - up to about 4 years.

The watch utilizes the Swiss tritium illumination system Pro-Glo T100, ensuring constant visibility of the indications for up to 25 years without recharging with external light. The light source consists of hermetically sealed micro tubes filled with tritium, emitting uniform, continuous light regardless of environmental conditions.

The system does not require prior exposure, maintaining full functionality both in complete darkness and underwater. High light intensity allows for quick reading of indications, which is crucial while diving, during nighttime operations, and working in limited visibility.

The model is equipped with a rubber strap with a width of 22 mm, finished with a steel clasp. The design is reinforced with a steel tube, through which telescopes pass, increasing durability and tear resistance. The strap fits well to the wrist, providing high wearing comfort and effectively preventing the watch from slipping.
