[arroyo479]

I am new to this forum and would like to know if anyone can help me to know if this watch is original? Or a copy? Works perfectly well, I do not know the year of manufacture, any help, thank you. Eta 2824-2

Thats a nice watch, and believe thats a gen.  The ETA has a module fitted for the complications it has, dubois-dépraz.
