Is my 1st gen Apple Watch waterproof?
I want to go swimming with my Apple Watch. But I’m not sure if that’s a good idea.
No. No Apple Watch model is actually waterproof. Only Water Resistant to different degrees.
The first Generation Apple Watch has a very basic water resistance allowing only for splashes from washing your hands or rain, but it is not rated for submersion or swimming.
