A factory reset feels like a very drastic thing to do just to simply move a watch from one phone to another. All the devices in this scenario are running Android, why isn't there a simple migration tool? For that matter, why can't I simply un-pair and re-pair the watch just like one does with every other Bluetooth device?
The main issue I have with doing the factory reset is losing my fitness data. I've been using Moto Body, which has an Android app, but no web app, so I want to be sure I have access to my data before wiping the watch.
Fortunately, I configured the Moto Body Android app to upload my data to Google Fit. The number of steps showing in the Google Fit web app matches what is displaying on my watch, so we are good to go there.
I already have Moto Body installed on the Nexus 6P, but it isn't showing any historical data, so while I have Moto Body configured to upload data apparently the Android app doesn't read that data. Very odd.
Ok, I am going to first remove the Moto 360 from Android Wear on the Moto X. Now we will do the factory reset of the Moto 360. Oops, don't have enough juice left on the watch, if memory serves it might need 80% juice to do the reset, I've put it on my Qi charging pad to carry on.
Unfortunately, the watch will not execute the pairing process until it has at least an 80% charge, so I will have to wait a while to pair it with the Nexus 6P.
