To verify the Rolex 18K gold buckles...

[Tim_HKG]

This is probably the one mostly found at the market



With different kinds of hallmarks, are there two buckles authentic Rolex products? If yes, what are the history and differences of all of them(3 types), like the period of production, for Day-Date, Datejust, or for Cellini models...etc.





Thanks in advance!
