Well why have the ad then I posted, they have to warrant it up to 50m faulty seals or not, if they don’t it’s false advertising, take your blinkers off.
What you think doesn’t mean blot, they have a ad with someone surfing with a Apple Watch 3 so you really think they won’t warrant it?
Nope it won't be covered as its water RESISTANT, not water PROOF. Big differance. If you read the Apple support page they even say Water Resistance is not a permanent condition and may diminish over time.
