Keep that watch away from your speakers/amplifier/magnetic fields/etc. and you will not have any troubles. Some newer watches have non-metallic/ferrous main springs to deal with the issue.
I met Roland a few weeks ago when we were both in NYC for the watch shows (his visit was as a vendor/presenter of course) and he is genuine a really nice person so I am not surprised.
I find it interesting that
Sinn only certifies
RGM for USA warranty service. Most Sinn watches have very basic ETA or Valjoux movements which means almost any watchmaker can service them but they only certify RGM.
