No; older models had snapback, (e.g. 634; or 774 etc in earlier serial numbers); new ones, + 1084, 1085, 1086 have driven, ie. Baionette caseback. Something between snapback and screwdown. Namely, they press & screw 1/4 or 2/4 turn alowing the alignement of the text on the back. For example, if I understand correctly Omega has similar system, Naiad lock. Eventhough I did not find pictures of this system on net for Panerai or opened my 1086; you can find pictures of Omega railmaste and their system...
