Well, recall after a year of operation. I definitely liked the watch. Came with a small jamb in the form of crookedly installed arrows, the compass was used at first, but there is also a lot, I tested water resistance only in the drum room, good. The battery lived for a year on the same charge indicator.! !! My opinion is buy this watch!!! I do not know what kind of glass but survived from regular contact with metal ( not much scratched)
