does 100m mean you can take it anywhere as i have read differing views can anyone clarify this for us all please.

100 meters is a minimum to allow you do dive or swim with your watch. 1 ATM=10 meters, as often only the ATM are written on the case back or the dials... For example, a Panerai Pam 249 is 3 ATM=30 meters water resistant...Do go on the beach with it, or yo...
