I had a similar watch in the Marines.  I bought this one after my thirty year old G-Shock was destroyed by a butter-knife-wielding "technician" at a local jewelry store bent the case while trying to install a battery (which they found they did not have).  I set the time and adjusted the wand body placement on the strap and put it on.  I take it off at night or when doing wet things but it has kept perfect time with the time signal from the NIST radio broadcast from WWV in Fort Collins, CO.  I like it enough that I did not detract for the slightly less-than-optimal cloth band that comes with the watch.  After about a month of daily use and on and off the wrist, the area around the hole for the keeper tang started to fuzz up.  It still holds okay but I see why people say they replaced the band with something they call a "NATO-spec band."  We'll see.  I plan to buy this watch for my two grandsons and for a nephew or two who have never worn a watch but like this one.
