I love this watch!  The size is perfect, love the white band but it does get a little discolored over time.  Not badly discolored though.  The price is good, its waterproof as I used it at the pool the entire summer last year.  So after swimming with it all summer, the band in one of mine is more ivory colored.  Not bad at all.

As for batteries, you can buy a pack of new batteries on Amazon and easily put a new one in.  I have done it twice now, very easy to do as long as you have a mini screw driver set, which we do.

I clean my band on a regular basis (probably once a week) with a spare toothbrush and a little hand soap or dish liquid.

Highly recommend this watch!
