Thank's to Domenico,
I can share you some pictures of the Rolex Clone movement we can find in some reps.
This is SIMPLY a 2836-2 Asia based decorated movement,
They get a glued button on the mass bearing and get one glued piece , to simulate the anchor bridge.
Some other pieces are lighter to simulate Rolex and this is bud.
To get conclusion.
IMO: Sure better to have one real Swiss 2836, than this one...
Your opinions about are wellcome.
