You can try taking apart circuit and coil looking for damage under the loupe but even if you can spot some then you may have trouble getting the parts. The coil can also be tested with a very low voltage tester that I don't think you have. So it may be more expeditious to look for a replacement mov't, its code is the first four digits of the model number on the back.
Hi to all members, I am somewhat of a newbie to watch repairs ( battery replacement stage ). My question is I bought a Seiko sq quartz watch from a charity shop and when I opened the back I noticed the old battery had corroded, so I gently brushed the area with a soft toothbrush, proceeded to change the battery but still not working. Any advice welcome. Rob
