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
