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).

The watch is powered by a battery.

Displays the current day of the month period from 1 to 31 December.

Measurement accuracy of 1 second. The maximum measured time is 12 hours.

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).

Mineral glass is currently the most widespread type of watch glass. It's very hard and has a high content of silicon thanks to which it's highly scratch- and impact-resistant. Mineral glass with a sapphire coating provides even greater scratch resistance. However, it doesn't mean that it's completely scratch-resistant.

Flip-lock Diver Clasp is the most widely used method of fastening straps and bracelets of watches. The buckle is also supplemented by a safety stop. If the lock is unloocked there is no accidental dropping of the watch. This is a very reliable method of fastening.
