yeah would not surprise me as when I was having other problems with it I strip it. it was a bit of a cut and shunt looked nice but way it was put together it was not going to last long

managed to get a set of decent 3602 hands dial a case that would hold a 3602 or a parnis 2927 is it out of it (parts always come in handy) so yeah still not manage to source a new crystal for the case it clicks on the front so has a metal ring it needs to clip into
