Dear Reg,
Tribal posted that he received a MBW1680 for repair which looked identical to the one you provided me.
IMO Tribal is an expert on Rolex. So it is possible that MBW changed the casing , bezel washer, dial etc. compared to the former model.
Given the facts I can't say or claim that the watch you sold to me is not a MBW and I want to APOLOGIZE for giving this community the wrong impression.
I hope you will accept it.
Carpe Diem
