First post so be gentle!
I've recently bought this old Leonidas chronograph with a Landeron 248 movement. The seller didn't give much of a description other than is was from the 40/50's and that it only ran for a very short time. Not sure how much he tested it as it happily runs for over 24hrs, although when I got it over the same period it was running nearly 2 hrs fast. I took it to my local watch maker who said the hair spring had been shortened for some reason and required replacing? After spending ages trying to find one, the watch started running to time of its own accord..
Anyhow, I have a few questions:
- Is there any way to date it more precisely?
- To my untrained eye it looks in decent condition, however is it worth getting the case rechromed and the dial cleaned up or is the preference to stick with the patina?
- As it is now running well should I still get it serviced given the issues with time keeping or should I leave it alone?
Cheers in advance!
