An innovative material developed in collaboration with Tohoku University in Japan and Eiwa Co. There are excellent mechanical properties in the cobalt-chromium-based alloy, it has particularly high resistance to wear and corrosion, and its biocompatibility is not negligible due to the absence of nickel.

An extremely hard, heat-resistant, scratch-resistant ceramic material. Sometimes, titanium carbide (TiC) is called high-tech ceramic and is also used as a heat shield when the shuttle enters the atmosphere.

One of the most common titanium alloys, also known as Ti-6Al-4V or titanium grade 5 (Titanium 5 Grade). A particularly high-strength and corrosion resistance material. It's used in a wide range of applications that require strength and low density, typically in regard to the aerospace industry and biomechanics (implants).

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!

An extremely hard, heat-resistant, scratch-resistant ceramic material. Sometimes, titanium carbide (TiC) is called high-tech ceramic and is also used as a heat shield when the shuttle enters the atmosphere.

A highly durable titanium alloy developed in Japan. The metal material with a composition of 15V-6Cr-4Al is three times harder than pure titanium and is characterised by minimal elasticity. Due to its specific properties, it's used to make heads on premium golf clubs.

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.

When enabled, watch makes every hour an audible warning sounds.

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.

A unique design that eliminates the adverse effects of mechanical impact, vibration and shock, thus ensuring a high mechanical resistance of watches.

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.

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.

The watch can be paired via Bluetooth with devices running on Android and iOS.

Is widespread alarm function. It provides repeated alarm - after stopping the alarm, the alarm will sound again in af few minutes.

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.

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.

A Folding clasp is the most widespread method of fastening watch straps and wristbands. It's a simple and reliable fastening method. If it accidentally unfastens, it won't unfasten completely, and the watch will remain on your wrist.
