An absolute bargain and well sober, especially for a 1511
As others have mentioned check the time keeping over 24 hours, if it deviates even by a second then it will need a service
Time keeping which is out more than a few seconds indicates a new circuit will be needed, let me know if this is the case, I can help out
A few common problems which are all solvable:
1) Quartz circuits go, they are available but budget £450
2) 'tinerkers' mess the motor unit up, again available and budget £450
3) magnetic minute wheels intermittently fail, this will identify by dropping a clear hour or two occasionally over night
Looking at yours it looks like a nice example, not sure ft the box is original but it might be as originally sold if it was an old stock item
The plaque is missing it's engraving, there is a place I know who can replace the plaque with the correct engraving.
Overall an absolute bargain, well done
Tom
