hi,
i bought exactly the same mvts. from bandmaniac on ebay!!!
with PH engraved and a weird shock protection on the balance jewel...
i tell him that they are asian clones, but he claims that they are genuines from far east ETA production line
anyway they're working perfectly and i'm gonna use 1 to swap an old 21J, but i don't know if ETA spares are compatible???
the question is : where ETA produces mouvements in the world and is there different mechanical quality???
