Frederique Constant also has a self-winding watch with bluetooth tech and a rechargeable battery.

Its self-winding clock told the time in days, hours, minutes, and seconds, from a face seven feet in diameter.

You can leave your self-winding watch in its box for half a century, dust it off, give it a few shakes, and it starts ticking again like no time has passed.

The watch is powered entirely by a self-winding rotor for the automatic movement and a combination of a kinetic generation and solar power for the e-Crown side of things.

Then it was a collection of self-winding springs or an “enchanted loom,” then a clock, an electromagnet, a telephone switchboard, a hologram and, most recently, a biological supercomputer.
