My Valgrange clone has the right number of jewels. There is a jewel everywhere the gen has one as well. This movement as described in the link I never saw, and none of my suppliers for movements has ever seen. And it does not even in a money sense make any sense to replace jewels with metal bearings.....
I much more guess that is a prototype that by Accident was used in a watch...
Thanks great link shame the movement is a load of sh*t... Right better get and order me some Swiss mechanics!

I got that one which puretime sells as a7750, but it clearly is the valgranges clone as the mainplate is much bigger and the levers to operate the chronograph are just the same than valgranges gen. I could compare with gen.
Basically it is a good movement, same weak spots as the gen...
