Question: how much is 20 bar water resistant?
Answer: Water Resistant 200 Meters / 200 Atmospheres / 20 Bar Though it might seem like it, this actually isn't dive watch territory. While 200 meters seems like a ton of leeway to scuba dive with, even down 10 meters, it's probably best not to risk it. But by all means, do some laps in the pool with these on.
