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.

For the Gear 2, the charging puck is as wide as the smartwatch face, but not as long.

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.

Bluetooth and NFC
Both chargers have Bluetooth and NFC capabilities so that you can tap them against a Samsung smartphone or tablet to connect the device to the watches' manager apps.
