I got this in USA last year. However my speedsonic is finally back from STS so bills to pay and this has to go. No trades thanks. Good condition all working with occasional sticky date change. Humming nicely. On new leather strap with GP buckle. It had the original box and instruction booklet. 198021 ref. 35mill serial number so circa 1972. £300 with box and papers. £250 watch and strap only. Be quick! In Cambridge, England. Can do RMSD.
The sticky date is it a basic cleaning and service issue or are any original parts need replacing if you know?
It has basically sat in my collecion, running, since I got it. Everything seems to work ok but obviously I am not an expert on these movements so cannot comment with any authority on it! I guess a basic service would be highly appreciated by the old girl - she is 43 years old!
