The SH3285 and VR3285 are the same movement. The SH/VR3285 is widely available and is used by many factories in their GMTs and explorer iis. Clean factory exclusively has the Dandong dd3285 movement which they use in the CF GMTs. There is no dd3285 explorer II yet. But we all hope cf will release one soon.AFAIK - somebody correct me if I'm wrong) GMF uses SH3285 movement while CF uses a -some say better - Dangdong VR3285 but they are not interchangeable, anyhow you can't get VR3285 anyhow, while SH3285 is available from AliX.
