My husband had put this watch on his wish list and I ended up finding it on the Amazon site which was a blessing in disguise.  The price of this watch was so much higher everywhere else and I had bought this on Amazon when the pricing was at a low and I jumping up for joy!  It's an atomic watch (you can just wait for the watch to adjust the clock on its' own or you can manually change the time yourself if you want) and it's solar powered so if its in the sunlight most of the day, the power on it is generated so you really don't need a battery for it (not that you have that options to use a battery for this watch).  The solar charge seems to last for a long time (maybe a month?).  My husband is an IT guy and he very practical.  This is the BEST gift I've ever given him.  He usually doesn't use/wear things that are not to his liking so if this says anything, it must mean he does LOVES this watch!
