Love the watch, HATE the band!! I'm a big guy, but the metal link watch band swam on me. You'd think Casio would make it easy to adjust the band size. NOWHERE in the instructions is the band addressed, also, NO phone number to ask for help. Went to UTube looking for help, no luck there. Finally went to the Casio web site, and after MUCH digging, found a phone number. The lady there gave me a URL with a video link with the information I needed. THEN I had to make a tool (filed down a tiny flat end screw driver) so I could pop out and remove the extra links so it would fit. Now when I wear it it constantly pulls out (OUCH!!!) tiny wrist hairs!! .....LOVE the watch!!!
