Pushing the button while submerged shouldn't damage the device. The whole purpose of this unit is to be able to record laps while swimming. It's also *supposed* to be waterproof.
Did you ever figure out how to fix it? Mine has started doing the exact same thing after taking a shower.
I just checked the manual for a swimming-capable Polar watch (the vantage m). Same thing. Don't press buttons under water. Also, I have a 50 m rated casio and a 100 meter rated timex watch. Again, manuals…
Same issue here. My 735XT unit is exactly 1 month old and is now unusable. Pretty horrendous experience with Garmin products.

Read the manual. It says not to press buttons while submerged. It is waterproof as long as you don't press buttons under water. Not observing this restriction is the best way to kill your watch. I understand that you don't like it, but that's how it is. If I want to press any buttons while swimming I just take my arm out of water for a moment.
Where in the manual does it say not to press button of this *waterproof* watch underwater??
Wow. That's like selling a car and the manual saying "Don't drive in the rain!"

Again, manuals for those watches say the same thing: Don't press buttons under water. In fact the only watch that explicitly allowed pressing buttons under water that I had in my hands was a 200 m rated casio g-shock.
Don't get me wrong. I'd love to have a watch with more waterproof buttons. Sadly, the industry standard for consumer electronic devices simply does not seem to be there yet.
I had a 910XT previously and a 310XT before that. Zero problems pushing buttons under water, for four years each. I'm amazed this is a common problem not solved.
