A 5 second swing indicates less than 7 days and that was the reading on my watch before this process started.

When the second hand swings forward 30 seconds, you apparently have a full 6 months of charge in the capacitor. You press a small button on the side of the case and the second hand quickly swings forward. Seiko kinetic watches have a charging indicator on the dial. When I placed the watch vertically in the metal charger (6 o’clock down) the power consumption of the charger immediately went up to 2.5 watts, a sure sign that the charger was working, and the watch was consuming power. I plugged the charger into an Arlec Watt Meter and got an idle power consumption of around 0.4 watts. I had already spent over A$100 trying to charge my kinetic watch but took the plunge with the Phillips charger, and purchased from Statewide Appliance Spares in Adelaide, South Australia.

The Phillips Diamondclean Toothbrush Charger is still in production and can be purchased for A$35 plus postage online.

So it appeared that the electrical charge could travel further than with other chargers. What appealed to me was that the charger was designed to accept a thick glass cup in which the rechargeable toothbrush was placed. I then came across some examples online of a Phillips Diamondclean Toothbrush Charger (HX9100) successfully charging kinetic watches. I came to the conclusion that the charging power emitted by the Braun charger(s) was simply not getting through to the coils in my SKA787. Kinetic watches have a handy charging scale built in so it is easy to see if the process is working. In my case the Braun 4728 (I also tried a Braun 3757) did not charge the SKA787 despite patiently testing multiple charging positions for at least 24 hours each. Order to get the toothbrush charger to work. For watch collectors, who share wrist time between many watches, that can be a problem. A fully charged capacitor will power a watch for up to 6 months, but it usually requires daily, or at least regular weekly wear, to keep it charged. A rotor which swings through the movement of the wearer’s wrist, spins a tiny generator, at up to an amazing 10,000 RPM, and charges a capacitor (think watch battery).

In those days of course it was a pocket watch.īut a kinetic watch is different. Yes, automatic mechanical watches go back as far as 1776 or early 1777 (Wikipedia) where the movement of the wearer causes a weighted pendulum or rotor to wind a spring which in turn powers the watch. Kinetic watches contain a unique movement in which the movement of the wearer charges the watch. The Seiko SKA787 is a comparatively recent version of a kinetic watch (I purchased it new in 2020) but kinetics have been in evolution since the first kinetic watch in 1986. Fortunately, I think I have a fix, at least for the SKA787 (shown left). I have a small collection of Seiko watches and I wanted a representative from the Kinetic range but I had read that there were difficulties keeping them charged.
