We are keen to sort a watch for my soon to be 9 Year old Son. 

The problem is his wrist is puny (he is in the 4th percentile for height and weight but is still healthy and happy and eats fine).

In an ideal world these are what we want: 

1) Clock

2) Stop Watch

3) Step Counter

4) Alarm or maybe 2

5) Sleep tracker 

6) Water resistant or ideally able to be swum/showered with, but this isn't essential, but minimum of lightly submerged capable).

7) Relatively inexpensive if possible. 

Anyone able to recommend one. Everything we have seen is either stupidly expensive ($150+) or doesn't fit him.
