Citizen Eco-Drive Chronograph Tachymeter CA0576-59E Men’s Watch

This one charges itself harnessing the power of light. The absence of regular batteries on one hand lessens environmental pollution while on the other, frees you from the anxiety of suddenly finding your watch halted to a dead stop. Since it charges automatically, you can use the chronograph without hesitation, as many times you want. The 1/5 second increment is a big advantage when you need to split time for finer degrees.
