Oh yea sorry fellas forgot to mention it is a synthetic sapphire which basically means mineral crystal. The chinese factories stopped making the 1950's style Panerai case with the true sapphire because of the cost. You can buy the original sapphire crystal for this watch on Ebay and have it installed....here is the link.....
