Tissot Le Locle Automatic Black Dial Silver Steel Strap Watch For Men - T006.408.11.057.00

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).

Automatic watches are powered by mechanical movement. They work on the principle of gradual opening of coiled spring. The energy of natural hand movements is transmitted during watch wearing through the rotor winding system, which automatically tightens the spring. Depending on the structure and length of the springs, these watches can work for varying periods of time, this ranges usually from 24 to 48 hours.

COSC (or C.O.S.C) is marking of watches, which meet the highest standards of accuracy. This certificate is issued mainly to watches with mechanical movements with automatic or manual winding. awarded by respected Swiss Certification COSC (Contrôle Officiel Suisse des Chronomètres - the Official Swiss Chronometer Testing Institute). The worst running accuracy error is -4 to +6 seconds. The watch is tested in five positions and at different temperatures. The certificate is awarded for each test piece of movement separately. Each piece of the watch that receives the certificate has its own certification number on a movement.

The watch displays the current date.

Watches marked with water tightness 30M/3ATM are designed for incidental contact with water (car wash, rain). 30M/3ATM indicates the degree of water resistance standardized by ISO 2281. ISO tests include temperature changes, depth, pressure (water and air) for different times under rest during manipulation with the operative part of the watch.

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.
