After peeling off a (seemingly nondescript) backing sticker, we find a shiny inductive charging coil.

The Moto 360 is the first Android Wear smartwatch to feature inductive charging. Previous Android Wear smartwatches like the Samsung Gear Live and the LG G Watch featured metal charging contacts.

Inductive charging works by passing an alternating current through a transmitter coil (charging dock), which creates a magnetic field. This magnetic field then induces a voltage in the receiver coil (pictured here), which charges the battery.
