I recently bought this Hamilton Private Label C. H. Case & Co Hartford CT
The seller said they had serviced it
and put a new main spring in, and adjusted it. I asked them
what their procedure was, and what they meant by adjustment.
I was impressed with their long detailed answer. It's interesting
the total sales price I paid was less than the cost of a regular
clean and oil service and a MS. I do hope he made some money on it.
