For the new Gear 2, Gear 2 Neo, and Gear Fit smartwatches, Samsung introduced new charging cradles. They're much smaller and less obtrusive than those that came with the original Galaxy Gear smartwatches. While the cradles look very similar, they aren't interchangeable between devices.
The charger for the original Galaxy Gear attached to the back of the watch, then folded over the front. There was a small cover that surrounded the watch face to hold the charger in place. The new model, above, just snaps into the back of the watch.
