I suspect this is a long-shot, but if anyone has a new or gently pre-owned 19mm x 16mm black alligator strap for a Patek deployant buckle that they would be willing to part with, I'd love to hear from you. I'm ideally looking for a black strap with grey stitching (the same look as originally came on the Ref 5056P), but I'll consider anything black alligator - so long as it is specifically made for a 19mm lugs and a 16mm deployant. Please PM me with photos, if possible, and asking price. Image is from an online listing I found - but the size is incorrect for my watch. Happy to pay via PayPal. Thanks!
