Hi. I have inherited a Bulova Accutron 2181F Watch from my Granddad. Unfortunately, I don’t know anything about it and it doesn’t seem to be working. I have read a couple of the threads on here and have tried putting a new battery in it (#344). When I do so, I can hear the watch humming but it doesn’t seem to work. If anyone can help me out with any information or advice both on the watch itself and any ideas on how to get it working, I would greatly appreciate it. Thanks.
