I think I have mentioned previously that I volunteered to check clocks and watches given to our local Hospice Shop before they are offered for sale, hopefully reducing the number of returns! A large number of specimens are ladies basic quartz "department store watches". Also one of the more popular movements is a Miyota basic movement. From time to time I would like to replace a failed movement in a good case with a working specimen which requires the removal of the winding stem. With most other movements I can locate an arrow depicting a "pusher" point but the Miyota has no indication whatever on how to disengage the stem. I have tried to determine this by dismantling faulty movements but have failed to solve the problem. This movement is metal not black plastic.
I would welcome help on this query to enable me to match up a few good movements and cases which I now have to hand.
