noobiest question.

Sorry for a dumb question. What exactly ATM stands for and how many feet (or meters) in 1 ATM?

[krustybrand]

1 atmosphere of pressure = 101kPa (approx) or about 14psi, or about 28ft of water

Thanks!

do remember, you need to discount some depth off cos of friction of the water.. when you swim or move, this create more resistance...

To be technically correct- 1 Atm = 14.7 psi= 10M = 33ft! (Salt water) at sea level.

Or if you need to go to 4 decimal points, DL this great little conversion program!

Yep!

AFTER you have had them tested!

Because a watch has a rating on the dial/backcase, doesn't mean it has been tested.

If the seller guarantees waterproofing/ depth rating, you have some grounds for hope. But I would still have the watch tested.
