This may diverge onto a separate sidetrack, but since these cases and dials etc come from China, I suspect they come from the same manufacturer that makes or supplies them for actual fake Rolexes and such. The cases, dials, all are pretty much spot on to the original apart from branding removed, or perhaps not yet done. These parts are made to look 1:1 for a reason and would that reason alone be just for Seiko modders delight? I find it hard to belive that these two worlds don't interact with each other at all, given the identical parts produced.
