I got one 1680 case from DW.
I do not used it.
some flow.......
Not 1:1 , and not accept GEN crystal and not Gen insert too.
Sure it's cheap, but best is to buy MBW cases.
Guys today talked with a watchsmith , I can not say you how this person is, he is not replica forum involved.
He seed me he sow this SA3135 already on a Gen Datejust.
He seed me there are around clone of the 3035 , 3075 gmt and 1570 too.
I'm attuned about guys...............
If somebody nether sow a Gen 3135.........I suppose all you sow.
That a comparative 3135 Vs. Sa3135.
I suppose that this SA3135 can fit all 3135 Gen case .
