My daughter was asking me for a watch and I wanted to get something appropriate for a 3 yr old but that she could grow into & eventually learn to tell time on...this is a great watch, she can put it on & take it off herself, the design/colors are great for little girls and I like the different info on the face when the time comes (that is, if she does not lose it by then, which she already has twice but such is life with a 3 yr old). My only real complaint w/ this watch is that the strap doesn't stay snug and loosens up over the day a little, which leads to it coming off sometimes, esp when taking jackets off, etc.
As far as fit- it is a little big for my 3 yr old but the strap is easily able to wrap further around underneath the watch face & is not uncomfortable for her at all. Really like it!!!!
