at first sight, are original. It is not unusual, as you very well know, for tritium hands to flake off or to become "mouldy". Loss of water tightness, a little humidity and the hands are..gone. The indices can also be affected, allthough because of a greater tritium content are not as "delicate" as the hands. Having said that, since the bezel is obviously fake, I wouldn't touch this piece with a 10ft bargpole...before...a full analysis and certification from Panerai or a local AD
