Most wireless charging pads have a single large coil in the center. In contrast, this aluminum-bodied Liberty Wireless Charger, by Eindhoven-based tech accessories company Zensd, features 16 small coils in an array. And the top surface is glass, allowing you to see the coils:

Beyond the "ooh" effect, I suppose the design does allow you to ensure, if you're charging multikple devices at once, that they're all properly situated.

An Apple Watch, depending on the type of band chosen, may not sit flat on the charger. For that situation Zens has also designed this somewhat awkward Apple Watch USB Stick, which can be plugged into any USB port, including one on the back of the Liberty.

Neither object is cheap. The Liberty runs $200, and the Apple Watch USB Stick rings in at $45.
