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 battery is charged with light energy. This eliminates the necessity to replace the battery.

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

Based on the calibration signal's reception from the GPS satellites, the watch will set the exact time and time zone. The setting can be done either manually or automatically, depending on the selected mode. The function can also be turned off and significantly extend the power reserve.

This feature is mostly found in solar-powered watches. It shows the battery charge status. If the indicator indicates a low level, just expose the watch to light and battery will recharge.

LumiBrite is a dramatically improved fluorescent luminous paint that quickly absorbs a greater amount of the light energy exposed to it and glows brighter and much longer in the dark. As its name suggests, LumiBrite starts glowing brightly in the dark and fades slowly. It is also completely free of radioactivity, ensuring safety for people and the environment. It is the ideal successor to both radioactive luminous paint and conventional fluorescent paints.

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.
