Fixing a Timex Electric (Dynabeat) Watch (battery) from the 1970's.....with battery will run only 3 to 5 seconds once shook. Battery compartment is clean & sanded contacts. I pulled crown / stem out & sets & moves hands (....when pushed in I can shake/rotate watch & will run for 3 to 5 seconds , ...... with stem/ crown pulled out , will not run....) I believe this is normal......The watch insides look very clean , no corrosion nor battery leakage....
Can any members give me some information on what direction I should take on this problem? I believe this is a battery conectivity within watch movement.....are there any diagrams showing the inside of the movement & how the movement works.....battery & mechanical. Thank you in advance for your help.....Dan
