Dear all My first experience servicing a quartz watch after servicing as an hobby my mechanic watches for many years. This is an old Certina that was given to me by a friend, with a ETA/ESA 9362 movement. Before service I put a new battery and the watch was working. After servicing the movement stopped working. i understand that there might be a lot of reasons for this (including the fact that I used technics and oils from mechanic movements on this one ), but at this stage I would only need to check if the electronic module is good. Don't have a quartz tester but only a multimeter. You will see on the photos that the battery contact is broken and needs soldering. With the battery in the movement I can confirm that the electronic module had power (1.57v). Question: what basic tests can I do with a multimeter to confirm that the electronic module is good? how to check if the coil is good and if there is pulse in the electronic module? what contacts should I use to test it? (I saw some videos on you tube but was not able to find the specific test procedures for the ETA 9362). Any information to help me check if the reason for the movement to stop is on the electronic or mechanic part of the watch is much appreciated. Many thanks
