I too lost the instructions for my generic 4 button digital watch and had to find the functions by trial and error and the results are below.
=========================

Select/Deselect Alarm, Hourly Chime or Both - Press and hold Lap-Reset Button, Start-Stop Button TOGGLES through the above options.
Select 12/24 Hour Mode - Press and hold Lap-Reset Button, Mode Button TOGGLES through the above options.
Select Stopwatch - Momentarily press the Mode Button, use the Start-Stop and Lap-Reset buttons to control.
Display Date - Press Start-Stop Button in normal time
display mode.
Display Alarm - Press and hold Lap-Reset Button in
normal time display mode.
Cancel Alarm - Press Lap-Reset Button in normal time

Hope this is helpful,
