Smart Lock won't recognize a Bluetooth device it's currently paired with

My s7 won't find my Garmin Forerunner watch even though the phone and watch are paired. It's worked previously, but has stopped. Any ideas?

Have you tried removing the device and re-pairing it?

This is odd. It doesn't show in the phone's list of paired devices, but it's definitely paired because the watch is receiving notifications and syncing with the app. I've also tried removing and reinstalling the device app and repaired that way...
