It just feels like there's something more elegant with mechanical watches than digital ones, largely because they run on well-engineered and intricate gears. But this one is has magnets.
It's possible to turn this into a mechanical but will most likely require more r&d and a heftier price.
And making it solar powered might interfere with the design of the watch, I imagine the weave to be akwardly placed on the face of the watch haha.
