How do these work? (I generally believe it has some sort of Piezoelectric generator)

What if it stopped (I didn't use it for a few days)?

Does it have any battery which after a few years needs replacement?

Any chance I can find out what battery Curren M8039B uses so I only open it once?

And see what's inside (schematics) before I risk breaking it?

much obliged

(I was once at a lecture where someone used a piezo generator with a device
that created eddies in forest fires so they could call in the fire on a
cellular network without battery or wired power. I thought it was so cool I
found this ten buck watch that worked that way.)

Hi,

I don't know such piezo-type of watch.

On the other hand I own a watch which contains an electromagnetic
generator which is driven by an automatic-type rotor. A supercap is
charged by that generator and serves as power supply for a quartz
movement. With a fully charged supercap the watch will work a few
days without arm movement.

I have my dad's old kinetic watch that was from the 50s or 60s and it
was touted as 'Self-Winding' No electronics though...

I understand this type of watch is popular again!

It hasn't charged by motion.

Maybe I can find a van der Graaf static egenrator...??!!

Probably more information here than you need.
