I recently found this on radio shack and i remeber i had mine still from five years back and i have never bought a new battery for it yet.
I've been using it for 11 months, every day. Water, steam, indsutrial chemicals, cooler and freezer... It's still working. Amaizing...
finally a stopwatch that takes normal abuse and keeps working ive dropped it into the water and dried it out and it keeps working we use it to time our remote control boat races.
