I bought this Lego watch on a recent cruise for my 5 year old. I had read the review on Amazon before and did not plan to buy it, but I bought something for his older brother and could not find anything appropriate on the ship for him except furry animal toys. So I bought this watch. We could get the exact size for his wrist by using the different Lego pieces and he worked out how to put it on and take it off before I could. It has never fallen apart while he wore it. However he has never worn it to school unlike his Flik Flak watch which he wore to school and which did fall apart, and on asking him why, he said, the Lego watch feels it can break any minute, but it hasn't, though. I guess that means it does not feel robust, but it is nice to look at and no problems as a time-piece.
