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). Movement: battery The watch is powered by a battery. Strap material: leather Leather is one of the most popular materials used in the manufacturing of Precision straps. It looks elegant, feels warm, and easily adapts to the wrist. Date The watch displays the current date. Stopwatch Stopwatch enables to measure time intervals. Water resistance: 200M 20ATM 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). Crystal: sapphire 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.
