What's in the box: Citizen BJ8050-08E Watch, Carry Case, 5 year Citizen US Warranty
Citizen Eco-Drive is fueled by light, it never needs a battery. Eco-Drive it's unstoppable. Eco-drive technology harnesses the power of light from any light source. Both natural and artificial light are absorbed through the crystal and the dial, than a special solar cell converts light and stores it as energy. The cell recharges continuously in any kind of light. It runs for at least six months even in the dark.
The watch case emaploys a s/steel base offering superior corrosion resistance, light weight and high strength, while the surface is specially treated for high hardness and enhanced scratch resistance. The rotating bezel, which is importantfor checking diving time, employs a reverse rotation prevention mechanism that prevents the rotating bezel from being rotated inadvertently in the wrong direction. The solar power generation function transforms solar energy into electrical energy to run the watch. Since solar energy is used as the power source of this watch, it has no need of regular replacement of the battery unlike the general diver's watches using the mercury cell, etc.
The screw down locking crown is securely locked in position through the use of ascrew-locking mechanism, the use of three O-rings results in enhanced air tightness and water resistance.
