I'm THANOS from cyprus and have in my possesion an UPO SWISS movement came from trusty.
as the most of the UPO's have the same issue with crown which refuse to screw down.
it has been already fixed,not at all ,twice.first time was sent back to far east and the second here in a local watchsmith.both of times none of genuine parts were used,so the crown didn't worked properly for more than a week.....((
Is there anyone that has already bought from ofrei or another source genuine parts(crown,tube)that fit to SWISS UPO?
posting a link for these parts,better from a european union source would be much appreciated...
