Up for sale is my Patek Philippe platinum (NOT white gold) deployant buckle, 16mm. Very hard to find these for sale, other than direct from an AD at full retail, which I believe is now close to US$6,000. Selling only because I’ve switched my platinum 5056P back to a more casual strap with its original platinum tang buckle. The deployant works perfectly and is in very nice cosmetic condition with only some very faint signs of wear. Pics should say it all, but if you need more, just let me know. Asking US $3,500 net to me via bank wire, Venmo, Zelle or PayPal (friends and family - no fees), including domestic shipping in the USA. Will also do “mask-to-mask” in the Philadelphia area. International shipping only after discussion of costs/logistics with potential buyer. Feel free to ask any questions. And thanks for looking. Mark
