Backup in TWRP, copy to desktop, install TWRP on new watch, copy TWRP backup to the new watch, restore backup. It'll be like you never left.
And instead of Titanium or reinstalling after a Gear Manager upgrade (or whatever), just do a backup of /data and then restore /data after the upgrade. Takes 15 seconds and you're back where you started exactly, no hassle.
