This is the crystal the seller shipped. It was described in his CT listing as:
"for sale Vintage original Heuer Autavia 2446 3rd Execution glass"

After I informed him the crystal was not the correct size for a 3rd Execution Autavia, I received the following responses:
#1:
"Very strange to heard this now that the crystal is not correct , the parts that I send it for you was mounted on a Autavia Rindt !!!!!!!"

#2:
"I‘m sorry is not my fault , the parts was mounted on my rindt"

#3:
"I offer only parts that I‘m sure they are mounted on a watch , Heuer used not always for 1 reference the same parts and if you search google under Heuer Autavia Rindt you will notice how many different hands are mounted for the Rindt , those parts that you bought from me was mounted on my Rindt that I serviced on tag Heuer and received the old parts ."

So maybe the seller has a magical Rindt...or a very rare version. But this crystal defiantly wont fit on my Autavia.

Can anyone tell me what this might fit?
