V_J_R,
Thanks for getting back to us. We're glad to hear you were able to get your Apple Watch paired with your companion iPhone once again.
If you're looking to temporarily disconnect your Apple Watch from the companion iPhone, which is what it sounds like based on your initial post, we would recommend just turning off Bluetooth from the Apple Watch itself. On the Apple Watch, go to Settings > Bluetooth, and tap Bluetooth to turn it off. This disconnects the watch from the phone, but does not unpair it from the companion iPhone completely. You can then just simply navigate back to this same area on the Apple Watch to turn Bluetooth on again, and it will automatically reconnect without the need to re-pair to your iPhone.
Have a wonderful rest of your day.
Kind regards.
