THIS IS MY SECOND HUNTING WATCH THE FIRST LASTED 6 YR. BEFORE THE BATTERY WENT OUT. THE ONLY THINGS I DONT LIKE ABOUT THESE WATCHES IS THEY WONT TAKE A REGULAR BAND AND A REGULAR BATTERY. WHEN THE BATTERY GOES YOU HAVE TO SEND IT TO CAISO TO HAVE IT REPLACED . IT EASIER  TO ORDER ANOTHER ONE FOR 30 DOLLARS.
