Apple Watch since Series 7 has had a 60GHz wireless USB transmitter in it that replaced the hidden pogo-pins used for OS recovery and diagnostics in the back of house at Apple Stores. They designed a specific sled that has an Apple Watch charger and the 60GHz macguffins, and then carriers that each model watch rides in on top to align to the charger and the 60Ghz connection.
Wireless USB at ~60GHz has (sort of) been a thing for a while for short range comms as a possibility.
One of the largest devices that ever used it was the Essential PH-1 and its snap-on camera module (and some other modules as well); the data was transferred over 60GHz USB while power and alignment was delivered by two pogo pins.

Ironically, it's also USB-C. https://sci.tea-nifty.com/blog/2022/03/post-eb2dde.html
