Hi there acwarp,

Thanks for posting to Apple Support Communities,

We understand your Apple Watch is making an unexpected sound. Let's start by being sure that your Apple Watch is up-to-date: Update your Apple Watch

If you needed to update your iPhone, test to see if the issue still persists. If it does, we then recommend to erase your Apple Watch to then re-pair it again Unpair and erase your Apple Watch

That should help. Let us know if you have any questions.

Take care.
