Finally got the update, too. Just left if on the charger at night, while my phone had a wifi connection.
For a short time I noticed a Motorola Sport watchface. I chose another watchface, but wanted to test the sports one, but it disappeared then..
I searched for a original looking watch band and found this on Aliexpress. It looks very nice, feels smooth ans has quick release pins. Don't know if it's genue leather, but I like it very much:
Did anyone figure out if Android 6 Marshmallow running on the phone is required to get the Android Wear 6 update?
You will get a notification on your watch.
Searched on the Germany Motorola website but didn't find anything. Can you provide me a link where to buy the original bands.
edit: found it: http://www.motorola.com/us/wearables/watch/moto-360-bands/Moto-360-%282nd-Gen.%29-Men%27s-46mm-Bands/moto-360-bands-mens-46mm.html
I had this problem at first, too. You just have to wait until the update has been downloaded completely, your watch will give you the option to update then. Make sure to be connected to a wifi network for some hours at least.
The "connected, running sync loop" relies on the Google Play Services 6.5 and does not depent on specific roms. I thinks this messages appears until the new Android Wear 5.0 update will be released.
