You are considering a brand new 22mm stainless steel fingernail buckle manufactured for perfect fitment for fine Panerai timepieces. Although made for buckle straps, this will also fit deployant straps as well but the center will be slightly loose. This is produced to the exacting standards by the manufacturer and will fit all standard strap for the 44mm Luminor Panerais.
