I recently bought a Khaki King, and noticed that when I forget to keep it wound - and it stops - it takes a LOT of spinning of the rotor to get it fully wound again. I've had one other automatic, and it only took about 10-15 seconds of spinning the rotor for it to fully wind. The Hamilton takes a good minute of constantly spinning the rotor. If I only spin it for 10-15 seconds, it pretty much instantly stops ticking. Is this normal?
