My godfather’s Congreve Rolling Ball Clock looks wonderful, but by his own admission, is a terrible timekeeper!

Back in the 70's and 80's when parts for Seiko movements were plentiful, Seiko recommend you changed the barrel complete I think every 5 or 7 years. These days you have to take the barrel apart and clean it all and put back as parts are more likely to be obsolete.
