Could a watch that winds itself with a pendulum work in space with no gravity? Could a pendulum or the self winding part be modified to work off the movements of the wrist in a microgravity environment?
To further this question could a set of various size pendulums be set at different angles to work as mechanical inertia dampeners even to absorb vibrations or microgravity?
