Ever seen someone take down a cheap quartz watch not intended for diving? I've seen some that don't flood. Not bad for $5, you might think, but I've seen them run slow, maybe 5 minutes a dive. I guess it's because the quartz crystal is spec'ed for 1 ATM, and vibrates too fast under greater pressure. ------------------------------------------------------- Roger Carlson w 310-812-0430 somewhere off Hermosa Beach, Cal f 310-812-1363 roger@ch*.sp*.tr*.co* h 310-frogger ------------------------------------------------------- Still using physics every day, especially the gravity part.
