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.

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!

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.

The watch automatically checks starting position of hands every hour, and adjust correct position if necessary. This eliminates deviation of the hands because of mechanical impact or influence of the magnetic field.

You lost your phone? By simply pressing a button on the watch, the phone alarm starts to ring and you can easily find it.

Illumination of the watch is provided by a diode (LED). Light is switched on by a touch of a button.

An illumination layer on hands which, after a short recharge, ensures illumination in the dark.

The watch is designed to eliminate negative effects of the magnetic field.

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

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.

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.
