One of the last best casio's in the market,this watch is a workhorse,is extremly accurate and it give you a lot of extras like dual time,perpetual calendar,alarm and more. It will give better service than a Rolex and more accurate. The G Shock used to be great but now they have plastic cases,this one still have a stainless steel case,its incredible for the price. Probably Casio will stop production on this one soon,its too good to be around this days.
