Recommend a watch service establishment in Oxford

[732NM]

I'm looking for some pointers to have a 1950's vintage watch serviced in the Oxford area.

The watch itself is not valuable, but has a lot of sentimental value for my nephew and I'd like to get it serviced and maybe a new spring installed, as it's only lasting about 12 hours per wind.

Any suggestions of people to be trusted at a fair cost in the area would be appreciated.

Watch Doctors over in Thame are excellent & have looked after me for the last couple of years.
