I would love some more info on this please. On WUS I see people also posting that fakes can never ever contain a genuine Swiss movement. But I question this and wonder what validation we have to base this statement on? Considering that if you go to alibaba X China express .com (something like that, huge popular China webshop) you can buy these really well made watches from brands like San Martin, priced usually around $250. What I've seen is that these brands often offer the buyer the possibility to choose movement, so if you pay say 150 more your watch comes with the SW200-1 instead of the Seiko NH35. Brands like San Martin have been around for a while now and have a very good reputation among low income watch collectors and I just wonder, when they claim they put the SW200-1 in the watch are they using a fake calibre? Maybe, but it seems like something someone would have caught and exposed at this point.
And I think it is safe to say that these factories who make watches for brands like San Martin, sometimes also do night shifts where they produce fake watches. Instead of putting that Chinese brand logo on stuff, you just go into night shift and start adding Rolex, TAG Heuer and other logos. To me it makes a lot of sense and if I was a Chinese business man I would definitely try to source genuine Sellitas (I mean, even private individuals can buy these movements for like 200 on Ebay) and put into my fakes to increase the likelihood of selling my bluff. If I can charge 1-2k for the fake Aquaracer, with a genuine SW200-1 I payed 100 dollares for, I still have a huuuuge profit margin on each watch I sell.
Who knows I know, I just think we should not be so quick and say that fakes can never have genuine movements, at least not for models that use these generic super cheap movements. In this global world of ours I imagine it would not be too difficult to source variable batches of Sellitas.
