I have 2 Kinetic watches that I seldom wear. Letting the energy deplete completely in the capacitor could weaken it in the long run. Hence best practice to always keep it charged.
To buy a SEIKO dedicated charger is very expensive. So, after trolling the web saw this cheap way to get the same result.
Use a Braun tootbrush induction charger to do the job.

Put the watch like so...

Within 24 hour watch has a charge rating from 0 to the 20 minute mark.
