This the type of watch l've had my eye on for quite a while. For a man's watch it's a big face screen date's and showing days of the week also plus a few more gadgets. You don't need any new batteries ot works off a little sauce the day light charges the battery built in the watch itself. Plus it charges with the artificial lights aswell. The glass is extra strong to protect the screen. Plus it's water proof and a five year guarantee plus additional twelve months if you apply on line along with the five year guarantee!
