OEM Panerai dark brown alligator 24/22 and 115/75 for buckle, brand new, never used. Came with my PAM177, but I mainly use the rubber strap. Asking $225, plus shipping from New York. I don't have an original Panerai bag because the strap came in the Panerai watch box. Not 100 percent sure of the exact model number, but I believe it is MX001SFV.

Herioc 18, brown leather with titanium buckle, 24/24 and 130/80. (Model # H18H24008; "antique brown" with ivory stitching from the company's "Historic" line; waterproof.) Comes with Heroic pouch and box. Asking $75, plus shipping from New York.
I prefer PayPal and U.S. deal. I have sold watches and watch accessories for years on forums and EBay as "swish77." Perfect feedback. Thanks for looking.
