I have just acquired a dent 2 day chronometer about 1847. It looks good seems to run well and is nice and clean, no damage to the balance spring, but it looses 3 seconds an hour. Should I leave it as is, or try and find a man who can have a go at rating it? I don't suppose it will ever be in a ship again. It would be nice to have your comments... Regards, Michael Delaney.
