Apple uses a magnetic charger that comes with Watch but now you can get a nightstand mode using the company’s official Watch Magnetic Charging Dock.
With the Apple Watch Magnetic Charging Dock, you can charge your Apple Watch in a flat position with its band open, or on its side. When docked on its side, your watch automatically goes into Nightstand mode, so you can also use it as your alarm clock. The Apple Watch Magnetic Charging Dock uses the same inductive charging connector that comes with Apple Watch. It charges both the 38mm and 42mm models. And it connects via the Lightning to USB Cable and Apple 5W USB Power Adapter.
Is there nothing inexpensive that Apple cannot make more expensive?
