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.

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.

Watches marked with water tightness 50M/5ATM are designed for incidental contact with water (car wash, rain), but also for surface swimming without diving. 50M/5ATM 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 and during manipulation with the operative part of the watch.

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. However, it doesn't mean that it is completely scratch-resistant.

The most widely used method of fastening, which is mainly used in leather and silicone straps. Simply turn on the buckle into the required holes as needed.
