Is a smart watch waterproof?
In order to be able to swim with your smartwatch, it must be at least IP68 or 10 ATM waterproof. Always check the manufacturer’s manual before use. If your watch is rated to 50 meters/5bar or less, it should only be subject to accidental splash; hand washing, dishes, etc. Never submerge it intentionally. If your watch is rated to 100 meters/10bar, it is suitable for surface swimming. If your watch is rated 200 meters/20bar, it is suitable for skin diving.
Which is better waterproof or water resistant?
In the simplest sense, a waterproof jacket offers the highest level of protection from rain and snow. While a water-resistant jacket offers a good, but lower level of protection. Waterproof jackets prevent all water penetration, water-resistant jackets can handle light rain but not prolonged exposure, and water-repellent jackets have a surface treatment that causes water to bead and roll off but may not withstand heavy rain.
