Full gold jubilee band stretch repair - who can do it ?

[Julnog]

Dear Rolex lovers,

I am the lucky owner of a 16018 DJ from 1979/1980 with a full gold jubilee hollow links band.

However, the band is heavily stretched, and I was wondering if the pins holding the links are also made of gold and who could do the job in Europe?

The information is quite easy to find for steel jubilee bands as the knurled bracelet pins are made of steel, but I was unable to find any information regarding the stretch repair for full gold jubilee bands (process and price)

Does anyone have any clue on this specific request?

Cheers
