Apple Series 3 watch chimes at 100% while charging

For the last several weeks my Series 3 watch will chime every minute or so once the battery hits 100% while charging (screen shows the power logo like when you first make connection to charger). While I'm not 100% it seems to have started after upgrading to WatchOS 5. Doing some Googling it seems a couple people have had similar issues over the years but aside from some troubleshooting I have not seen anyone with a fix/answer. Below is what I've done thus far:

1.) rebooted watch (both soft and hard)

2.) un sync and re sync watch from my phone (restoring backup on re sync)

3.) tried wife's Series 3 charger cable (and power brick)

4.) used different outlet in the house

5.) ensured plastic packing wrap was removed from the charger puck

The wife's watch can charge on my cable without this issue and my watch still chimes on her cable so I think it's something with my watch. Aiside from this it's working fine, battery life is two days just like it was when new (its 14 months old). Neither the watch of the charging puck are hot (not even warm) when charging. I do NOT use any charging accessories/stands/etc, just what came in the box with the watch. Anything else to troubleshoot? Is there a way to get logs off the watch that might indicate an issue? I could bring it to Apple store obviously, what sort of tests/checks do they do there?
