Your smartwatch needs charging every night. This one never does.
This watch has no battery inside it. None at all.
It winds itself from the movement of your arm, and you can watch it happen through the open front.
No charger. No cable. Nothing to plug in, ever.
Most watches hide the best part
Turn most watches over and all you see is a plain metal back.
Turn this one over and you can see the movement inside, still turning while you move your arm.
That is what powers it. Not a battery. You.
