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.

Mostly of rubber, resins or silicone. This type of material has high flexibility, is hypoallergenic, water resistant, and does not absorb sweat.

Displays the current day of the month period from 1 to 31 December.

Limited Edition is a special production lot of watches of limited quantity distributed all over the world. Each piece is unique, usually by having an embossed numerical designation - serial number. Most are also available with a special limited packaging.

Super-LumiNova is a luminous layer that is applied to the hands, indices and digits on the dial. After sufficient activation by sunlight or artificial light, your watch face will even be readable in the dark. It's different from other luminescent materials (tritium, GTLS) in a way that it's not radioactive but still very clear.

Watches marked with water tightness 500M/50ATM are designed for swimming, snorkeling, and for professional diving with breathing apparatus. 500M / 50ATM 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.
