Titanium does not contain additives such as nickel and lead and therefore is mostly suitable for allergy sufferers. Causes no adverse reaction with the skin. It is hard, color stable and very lightweight.

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.

Measurement accuracy of 1 second. The maximum measured time is 12 hours.

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 100M/10ATM are designed for swimming and snorkeling and free diving without breathing apparatus. 100M/10ATM indicates the degree of water resistance standardized by ISO 6425. ISO tests include temperature changes, depth, pressure (water and air) for different times under the  rest and during manipulation with the operative part of the watch.

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.
