Hello everyone…
I recently got an Apple Watch and I’m wondering if it’s safe to swim with it. I’ve heard conflicting information about whether Apple Watches are waterproof and suitable for swimming. Can anyone clarify if swimming with an Apple Watch is okay? Are there any precautions I should take to protect the watch?
Hello guys 
Yes you can use Apple Watch Series 2 and later models for shallow-water sports, such as swimming in a pool or even in the ocean, however, models other than Apple Watch Ultra or later should not be used for activities that require submersion below shallow depth or at fast speeds, such as diving or water skiing.
Make care to clean it well after swimming in the water.
I took my GoPro into the ocean once and didn’t rinse the waterproof casing. A few days later, the hinge was completely corroded, with salt crystals developing in nearly every crack and crevice.
Swimming with an Apple Watch is generally safe, as it is water-resistant and designed for swimming. It can track swimming metrics and withstand immersion up to a certain depth.
