Wotancraft produces many nice straps for Panerai. Most of their straps are made to generate vintage/old looks on your Panerai. The one I have ordered is the limited edition of 20 straps. Its name is "The X.M.A.S Originale", price: USD 289. I intend to use it with my PAM 127. It took about 2 weeks for delivery.
The package was sent to me via EMS
Inside the package
When the box is opened, you will see a small leather pouch and a card .
When the pouch is opened, you will see the strap and a submarine key holder (actually I bought this strap because of this key holder hehe :P )
On my PAM 127
I just love this strap!
