Why is the Apple Watch Series 3 being promoted in Apple Store as swim proof?

Apple Customer service indicated that since the watch was not put in swim mode it would not be splashproof, swimproof, surfproof. I am very disappointed the way I am being treated. My wife bought the watch because we are around a lot of water.

Even Apple Store claims splashproof, swimproof, surfproof without ever mentioning the downside that these features deteriorate over time. (seems like a escape clause to cover any problem out of warranty). Apple should disclose that the waterproofing deteriorates over time, I would have still bought the watch but would have not worn it around water.

I am an Apple fan. I even own quite a bit of Apple stock. I was a fan because Apple creates and sells good products and is very helpful. My current experience from Apple customer service has been horrible. They kept indicating that it was my fault for not having it in swim mode. They offered to service the watch for 3/4 price of a new one, not helpful. They also indicated to me that they would call me June 9 2022 between 10-11 they did not.

This is not the way Apple became great. If nothing else, please disclose on Apple Store that the proofing deteriorates over time.
