I serviced a Pepsi variant of one of these a while ago. This one is the plain black bezel version. It's been well used, but not abused. Although the crystal has seen some welding I suspect. Caseback is nice and clean and no evidence of Edward Scissorhands doing any tinkering. After the usual check and a brush down to remove crud, the caseback was removed and the battery taken out. Then the hands could be aligned and removed. With the hands off and safely stored the dial is removed, exposing the day/date wheels which come off next. Beneath the day/date wheels are all of the dial side parts which are removed without and problems noted. With all the bits put away, it's flip the movement over to do the working side. Here I've removed the train bridge, exposing the step rotor and the wheels. The step rotor has been removed and captured in its own plastic container (it's a very powerful mini-magnet!). Similarly, the circuit assembly and coil block are removed and put into safe containers. With the last of the movement parts out and safely stowed, it's time for the case. No dramas and everything is now ready for cleaning. And does it need some cleaning! More to come.
