Here is a watch I made back in April with a built-in flashlight.
2ea 3mm led's for the flashlight
CR2450 battery for 15 years run time - less with lots of light use
Guts out of a $15.00 watch off ebay - Casio Waveceptor WV59A - never need to set it
I cut the crystal out of a peace of window glass.
The band is an old belt.
6 refrigerator magnets for the buckle.
2 external pizeo's for a loud alarm
Built-in tool for battery change and tightening screws
Just shake hard to turn on the backlight
