Warranty card
 
This piece is 100% guaranteed authentic and in excellent condition. There are a few superficial scratches in the case consistent with light wear. There is a small smudge in the tantalum case below the 6 o’clock index which is not terribly noticeable. The lugs have a few spider marks from tool slippage (common with Panerai). The crystal is perfect with no scratches or marks.
