CERTINA DS ACTION DAY-DATE POWERMATIC 80 C032.430.11.051.00

Case material: stainless steelStainless 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).

Movement: automatic Powermatic 80Automatic watches with Powermatic 80 technology are powered by mechanical movement. They work on the principle of gradual opening of coiled springs. The energy of natural hand movements is transmitted through the rotor winding system, while wearing the watches, which automatically tightens the spring. Power reserve is up to 80 hours.

Date – the day of the monthDisplays the current day of the month period from 1 to 31 December.

Date – the day of the weekDisplays the current day of the week. Abbreviations days are in English (in rare cases a day of the week can be in German or in another language).

Water resistance: 200M/20ATMWatches 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: sapphireSapphire 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.
