I am looking to fully restore/service/clean my father's 50s/60s Longines Flagship. Crown is missing, glass needs changing and the silver dial has quite a few age spots on it. It was regularly serviced and used daily up until the late 1980s when it became a struggle to find a jeweller to service it and therefore started losing time badly.
I travel alot between Switzerland and the UK and was wondering if anybody had any thoughts about taking the watch to Longines (sadly now Swatch I suppose) in St Imier as opposed to a local watchmaker.
The people at Longines have been very helpful over the phone and seem to know about the model etc and the trip would be worth it just to see their museum. I also like the idea of original parts but do you think an independent Swiss watch repairer (I have found a reputable one whose advertisements indicate he does this kind of restoration) or one in the UK would do a better job.
I doubt the watch is worth much but it has great sentimental value so I am not concerned about cost, just the quality of work in terms of physical presentation and timekeeping as my father would like to wear it as his everyday watch once again.
Sorry for long message but any advice/ comments would be much appreciated.
