Gabb Watch 2 is available in two colors (silver, in addition to the original Gabb Watch space gray). Also, the Gabb Watch 2 comes with an updated black watch band.
All other differences are software upgrades. All of the following updates will be on both Gabb Watch and Gabb Watch 2. A software update will be rolling out to the Gabb Watch in the month of July.
To update your Gabb Watch software to the Gabb Watch 2 software, on the watch, go to the "Update" app in the Settings menu and click "Check Update". It's the last app in the Settings menu and looks like a down arrow. These software upgrades include the ability to add up to 25 contacts, 4 new themes, 8 new wallpapers, the flashlight app, and Gabb Go updates like repeating task functionality, 3 new pets, and mystery moves for all 9 pets.
