Stainless steel 316L (Stainless Steel) is a very durable material that theoretically can not be destroyed. It is hard (non-bendable and non-crackable), color stable, antiallergic (does not react with body fluids and therefore no metal components are not released into the skin and flesh) and has anticorrosive surface (the surface is resistant to oxidation and corrosion. Moreover, it is also resistant to fresh and salt water).

Automatic watches are powered by mechanical movement. They work on the principle of gradual opening of coiled spring. The energy of natural hand movements is transmitted during watch wearing through the rotor winding system, which automatically tightens the spring. Depending on the structure and length of the springs, these watches can work for varying periods of time, this ranges usually from 24 to 48 hours.

Leather is one of the most popular materials used in the manufacturing of Precision straps. It looks elegant, feels warm, and easily adapts to the wrist.

Watches marked with water tightness 300M/30ATM are designed for swimming, snorkeling, and for professional diving with breathing apparatus. 300M/30ATM indicates the degree of water resistance standardized by ISO 6425. ISO tests include temperature changes, depth, pressure (water and air) for different times under rest and during manipulation with the operative part of the watch. The dive models, subsequently performs the test of resistance to salt water and the ability to cope with the watch positive pressure (decompression simulation).

Sapphire glass in the watch was made in a laboratory by melting aluminium oxide (Al2O3) in the presence of hydrogen and oxygen at 2000 °C. After crystallisation into the corundum 'pear', it's cut and further processed into the desired shape and size. Sapphire glass is the hardest glass used in watches. It would be second behind diamond on the scale of mineral hardness, so it can only scratched by diamond. Its only disadvantage is its fragility.

The most widely used method of fastening, which is mainly used in leather and silicone straps. Simply turn on the buckle into the required holes as needed.
