I recently got a Bulova 11AL from a local jeweler who asked me to fix it up for him. He knows I'm an amature but said he'd give it to me it practice on and told me to bring it back to him in a week to see what I can do. He told me It was gaining. Which it was. Around 720+ seconds per day. After my service and regulation I got it down to 70 seconds per day. The regulation arm wont go any further without touching the beat error regulation arm. If anyone has any helpful advice for me to use I would seriously greatly appreciate it.
(By the way, the balance jewels are cleaned and lubricated)
