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).

Eco-Drive is a power technology of Citizen watches. The solar cells, which are under the crystal, convert light energy into electrical energy, which is stored in the battery and powers the watch. This eliminates the need for battery replacement!

Subdial shows the time in 24-hour format. For example, the main dial shows 3 hours, which equals 15 on a subdial.

Part of the watch is an alarm clock that can be set at different times. When activated, the alarm sounds.

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).

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.

The watch is equipped with pre-programmed (perpetual) calendar, which recognizes long and short month and leap years. This eliminates the need for setting the date for long and short month.

The watch Receives signals from atomic clocks, usually once every 24 hours. Deviation of atomic clocks is only one second in three million years. Therefore,watches equipped with this technology to receive radio signals are extremely accurate. Their owners can be assured that their time and date is always exact. This watch is receiving a signal from the transmitter, which are located in Europe (United Kingdom - Anthorn, Germany - Mainflingen), USA (Fort Collins, Colorado), Japan (Fukushima and Kyushu) and China (Shangqiu). In the event that you find yourself in an area that is not covered by the signal, your watch still maintains very high accuracy, and after returning to the coverage your time is again automatically adopted.

Stopwatch enables to measure time intervals.

Display simply shows the times in selected major cities and areas of the world.

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.
