You are considering a brand new 24mm stainless steel pre-V pre-vendome buckle in a black PVD finish manufactured for perfect fitment for fine Panerai timepieces. Although made for buckle straps, this will also fit deployant straps as well.
This is produced to the exacting standards by the manufacturer and will fit all standard 47mm Luminor Panerais. Please note that buckle straps for 47mm Panerais are 26mm at the lugs and 24mm at the buckles.
