Question

My watch is water resistant to 5 atm, what is that is feet?

Answer 1

Jon P's answer of 165 tf is for 6 atm. I think he forgot that you start at one atm at the surface and that it's included. Here's the break down .

Surface 1 atm

33ft        2atm

66ft        3 atm

99ft        4atm

132 ft     5 atm

I wouldn't take your watch down to 132 ft ( I've taken an ironman rated at 300 ft to 150 and it died) as it's "water resistant" not waterproof.

Answer 2

165 ft.
