You can contact Dirk Grandry through <dirk.grandry@pandora.be>. By the way, don't tell him the strap is for a replica watch
I love Dirks because they follow the same design as the PAV-90, my all-time favorite strap, and the NOS Dirks with logo buckles are awesome. But for the variety and quality of the hides, Mario Paci and Strapmasters are my top aftermarket brands.
