I knew this to be already. This purchase was intended to be a Christmas gift. The one that I hold for several months already is completely forgotten: it is light, discreet and above there is no need to reset the time, this is done automatically. Ditto when switching to winter time. The fact that it is charging in the sun or the light takes away the recurring problem of battery changes every two or three years, with the risk of sealing loss that entails. Remains to be seen what this will give the duration in time .The only negative was made to these accolades, lighting dropped me pretty quickly but it is secondary. Former military, I was able to judge on the field other Casio G schock: weaknesses, it is the bracelet and the plastic casing. Their strengths: the Robustness of the housing and incredible durability of their lithium battery. I own two since 1987, I have never changed since the battery and the first is just go let me go, incredible but true!
