Case material: stainless steel
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).
Movement: solar power (ECO DRIVE)
Eco-Drive is a power technology of Citizen watches. The solar cells, which are under the crystal, convert light energy into electrical energy, which is stored in the battery and powers the watch. This eliminates the need for battery replacement!

Water resistance: 30M/3ATM
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.
Crystal: mineral
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.
