Movement Identification Help

[Mollusk81]

This is my first post and I hope this is in the correct forum. If not, I apologize in advance.

I recently received this Tiffany movement and I have been trying to get some information on it. I was told that it could have been Touchon. I spoke with a couple people regarding that possibility & both told me that they didn't believe it was Touchon because of the bridge layout. Their thoughts were Patek Philippe or possibly made by Tiffany itself for the few years they made watches before Patek took over.

I was hoping someone here could let me know either way if it is by Patek Philippe. The movement measures approx. (27.8mm) in diameter. It is only marked Tiffany & Co. New York 20020. The dial is also only marked Tiffany and is a snap on style dial.

Any information is appreciated.

I would say it is not by Patek Philippe - the serial number (if it had been Patek) would date the movement to 1865 and it is not that early. In 1865 the movement would have been key wind or a very early keyless lever movement.
