The main advantage of ceramics is the high hardness and color stability. It's harder than stainless steel, and therefore has a very high resistance to scratching. It is hypoallergic and therefore suitable for all with increased skin sensitivity. Its main drawback is its fragility - can break during strong impact.

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.

The watch is powered by a battery.

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.

A one-way valve which opens automatically or manually when the internal pressure increases due to the accumulation of helium, the helium is suddenly released and the pressure in the housing is equalised with the ambient atmospheric pressure.

Rotating bezel is used to measure short measuring sections, up to 60 seconds. The bezel is designed to set the starting position. The start is set simply by turning the bezel to the starting position, reading of time is done directly on a bezel.

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 1000M/100ATM are designed for swimming, snorkeling, and for professional diving with breathing apparatus. 1000M/100ATM 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.

This is closing in which the buckle closes reliably on two sides. It resembles the shape of a butterfly after opening. During accidental opening, the watch stays on the hand.
