where to mount gps / watch?

Hi,

I was curious about experiences concerning mounting a watch onto your surfski? I have a garmin 305, which i would wrap around my footstrap, but I'm afraid the straps of the watch won't hold it when you go through the surf zone because the footstraps fully catch the wave when going through the surf... Any better solutions for this?

regards,
vincent

With the velcro on the watch band it wont come off.
