As a parent, you have to consider quite a few things before getting that watch for your child. You don't want to end up buying something costly because kids play, roll over in the mud, have actual fights with their friends, and so on and so forth. All this happens while the watch is ticking in their wrists. It may just stop ticking after all that. So, chances are that the watch will get lost or broken within a year (it may not last even a month though).
You also need to consider the maturity level of your child. Just because the elder one wears an analog watch, doesn't mean that you get one for the younger as well. Of course, if you are teaching your child to tell time, then an analog watch will be perfect. However, if the kid is too young, you may want to go for a digital watch.
Your child's likes and dislikes also count. Children love watches with their favorite cartoon characters or with bright colors. So, you may want to consider that and not buy something very plain and boring which your child may just throw away within a couple of days.
Also, if your child loves his watch too much, he is not going to take it off, ever! So, make sure that you get a waterproof watch. Even if he decides to take a bath with it, you won't have to worry about it too much.
So, here are a few examples of the best watches for kids. Take a look and maybe you will find something that really excites your kid, is cheap, and may just survive for some time.
