Mostly of rubber, resins or silicone. This type of material has high flexibility, is hypoallergenic, water resistant, and does not absorb sweat.

Tough Solar is a power technology of Casio 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!

Mostly of rubber, resins or silicone. This type of material has high flexibility, is hypoallergenic, water resistant, and does not absorb sweat.

A choice of two ways to display time in 12 or 24 hour format. For example, 3:45 or 15:45.

5 independent alarms for flexible reminders of important events. You can set 5 different reminders.

A special sensor measures the air pressure, measured values ​​are shown on the display of the watch. The measuring range is 260/1100 hPa. The display unit is 1hPa. The display shows the graph of atmospheric pressure. The chart changes are recorded automatically at regular intervals. According to the changes in the graph one can easily determine changes in weather.

Countdown timer with a maximum time of 1 hour. Example: set a countdown for 30 minutes. After 30 minutes alarm starts.

This feature displays the current Moon phase. The Moon phase is displayed as a special icon on the display of digital watches or in the small dial of analogue watches.

The display of the watch shows current state of the tide in a simple graph. This view is based on the current moon phase. By entering latitude and longitude of your position you can easily display current tide level.

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.

When you start the yacht timer, the watch beeps after each minute had elapsed. During the last 10 seconds, the watch beeps every second. This function popular for yachting but it can be used also for other sports, such as running. The settings range from 1 to 10 minutes.

Built-in compass displays the North and other cardinal points. The display additionally shows angle towards the goal from 0 to 359 degrees. Resolution/accuracy of compass is 1 degree. The compass is one of highly recommended features for all adventurers, and hiking and outdoor lovers.

Construction of watches is designed for operation even at temperatures down to -10° C.

EL panel illuminates main dial and thus ensures easier readability. The auto function provides automatic switching of illumination by leaning your hand to the face. The illumination is activated by a sensor, which is activated by turning your hand by 45° this illuminates the main dial.  Moreover, the watch is equipped with a light sensor that activates the diode only during twilight or darkness. This feature can be easily turned on or off. When auto function is deactivated, activate illumination by touch of a button.

The display shows the current date. It is pre-programmed, so there is no need to set short and long month and leap years. Most watches have this pre-programmed date until 2099th.

Elapsed time, split time and final time are measured  to the nearest hundredth of a second. The maximum measured time is 24 hours.

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

The sensor may measure the temperature at -10 ° C / + 60 ° C. The temperature is measured in both, degrees of Celsius (° C) and Fahrenheit (° F). Resolution is 0.1 ° C or 0.2 ° F.

Barometric sensor records the atmospheric pressure from whitch an altitude is calculated. The altimeter can measure elevation of up to 10.000 meters above sea level.

The watch can record altitude points. Each of these points includes the altitude, and date and time of recording. Maximum and minimum altitude is stored as well so you can trace back what altitude you were at at a given time.

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.

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).

Currently the most widespread type of watch glass. It's very hard and has a high content of silicon thanks to which it's  highly scratch- and impact-resistant. However, it doesn't mean that it is completely scratch-resistant.

The most widely used method of fastening, which is mainly used in leather and silicone straps. Simply turn on the buckle into the required holes as needed.
