I am thinking about purchasing my first Panerai because i have fallen in love with their case shape, history and sheer aesthetics. I have been reading about there different models lately I just think it's about time i embraced the whole Panerai world! I would like to start with a Marina. However, i don't know the first thing about Panerai watches as I have never owned one. There is one in particular I quite like the look of. Can you guys advise if this watch is genuine. It's been marketed as an OP6746.
