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.

Displays the current day of the week. Abbreviations days are in English (in rare cases a day of the week can be in German or in another language).

Besides the main watch time, you can display a second time. Ideal for people who have friends in another time zone and want to find out what is the time in their zone.

With two cooperating technologies (GPS and radio reception) watch shows continuosusly exacty time, no matter where you are. If you are in the area where the watch can not receive radio signals as the exact time set by GPS satellite. Moreover, thanks to communicate with the GPS satellites watch also sest the current time zone and current daylight saving time.

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.

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.

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.

Watches marked with water tightness 200M/20ATM are designed for swimming, snorkeling, and for diving with breathing apparatus. 200M/20ATM 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.

Flip-lock Diver Clasp is the most widely used method of fastening straps and bracelets of watches. The buckle is also supplemented by a safety stop. If the lock is unloocked there is no accidental dropping of the watch. This is a very reliable method of fastening.
