Hi bigdaddy73,
If you are having issues with your Apple Watch Bluetooth not functioning as expected, you may want to try some basic troubleshooting steps. These can all be found in the Apple Watch's manual, available here -
https://manuals.info.apple.com/MANUALS/1000/MA1708/en_US/apple_watch_user_guide. pdf
First, restart the Apple Watch and test again - see page 89 -
Restart Apple Watch. To turn off Apple Watch, press and hold the side button until the sliders appear, then drag the Power Off slider to the right. To turn Apple Watch back on, hold down the side button until the Apple logo appears.
Next, I would try resetting the Apple Watch's settings - also on page 89 -
Reset Apple Watch settings. On Apple Watch, open the Settings app from the Home screen, go to General > Reset, then tap Erase All Content and Settings.
After the reset finishes and Apple Watch restarts, you need to pair Apple Watch with iPhone again—open the Apple Watch app on iPhone, then follow the instructions shown on iPhone and Apple Watch.
If the issue is still present you may want to restore the Apple Watch. Note that this erases all contents and settings. See page 91 -
Erase contents on Apple Watch. On Apple Watch, open the Settings app from the Home screen, go to General > Reset, then tap Erase All Content and Settings.
Thanks for using Apple Support Communities.
Best,
Brett L
