Good question Pete and one I'm afraid I can't answer. I'd like to think the BB serialization is such that there wouldn't be another with the same number.
The only watch of mine my wife ever commented on was my PVD Panerai 202/A on a GSD Crazy Horse strap. Go figure
In general, she doesn't even notice.
She does, however, love her Patek 24 Rep which is her daily wear
Welcome Sammy from a fellow New Englander. Looks like you have some nice Panerai AD swag up for sale
I think we all wandered in here with one brand in mind and some have settled and others are still multi-brand oriented...
I'm a mix of Panerai, Vintage Rolex and others (IWC)
Have fun and welcome to RWG
