Pokemon Kids' Quartz Watch with Plastic Strap, 16

Q: Will this fit a 25 year man?

I’m 31, 185lbs and it fits me in the last hole.

Q: can someone please explain how to set the time? i lost the directions and the buttons on the right don't seem to do anything. thanks!

Further to the answers below: The LEFT side 3 buttons are not functional, only for display and symmetry. On the RIGHT side, the upper of three buttons is to turn on the multi colored lights under the characters, which will turn off automatically. The LOWEST button is the function button, and scrolling through it will give you the month, day, hour and minute. The MIDDLE button will change the number for each of those previous functions, but ONLY in ascending order. E.g., if you are at 35 minutes and you want 33 minutes, you will have to go up from 35 to 0, then 1-33 and stop. For the hours a "P" will show for the PM 12 hour cycle, although once set you will not see AM or PM. To save all of the above date and time settings, press the bottom function button one more time and it will show the new time.
