WS 6: Repairing a Caliber PUW 910: Circuit and Coil removed
Here is the promised better shot with more light on the
movement. A nicely engineered compact movement. I lifted the coil out of its
place to show you how flat this movement really is. The left most jewel is the
rotor jewel, then in a line, the jewels of the gear train. In the foreground
right, you will see that unusually shaped sloped bank, that is the space for the
resin covered circuit mounted on the underside of the circuit board. You will
see pictures from top and bottom of the circuit later. Next to stem you will
also see the pusher to push down the setting lever in order to remove the stem.
And if you look very closely, you can also spot the castle wheel just left to it. Many times if a removed stem does not go back in place, a dislocated castle wheel is the reason. It can slip past the lever that holds it in place when the crown is pulled out to set the time. Not a big deal to fix that buy the way, but to do it, you will have to work on the dial side and simply push it back and make sure the lever runs nicely through the collar of the castle wheel. But let us come back to this project. On the next page you will get an idea, how small those quartz watch parts really are.
