‘Driven’ back

[TikTok]

The Panerai website describes some of their watches have a ‘driven’ back as opposed to a screwdown.
Would I be right in saying that this is a press fit back.
Tried searching and some comments in ‘other places’ say that it has some sort of bayonet fitting but this isn’t clear.
Thanks in advance for all answers.

Yes, or "snap on back".

Whatever the term, I feel like it's a regression from the screw down backs, even if functionally it seems to result in the same water resistance.

Driven used to mean a fastener was used in watchmaking. Snap caseback was different.

But with Panerai who knows?

I really don't know. A bayonet back seems ok for me, the point is that nobody have seen any picture of it.

Its bayonet back. Just to point out, it is in substance irrelvant if it is snap on, bayonet or screw. Declared wr is 100m. For example, sunno water computer has bayonet fitting. Naiad omega is bayonet. PAM 914 has screw back, but at the same time has snap on glass on that same back?? More or less each crystal is snap on and nobody cares.
That said, if you like the watch buy it.

Unfortunately, the 914 does not have a sapphire glass on the back for at least last 3 years of production... I have one from 2021, and just a regular SS caseback. :(

The PAM's are just "pressed" up against the case with the crown lever. I like the look and the novelty of "popping" the lever open and closed.
