I'm pretty sure it's the same movement as used in the Graham and GP...

... for the following reasons:

1. The Graham 1695 movement (it was used in the Graham first, GP SF came later) was a Jaquet as well.
2. The Panerai layout is exactly the same as the Graham's and the GP's. This is not your everyday layout, with a foudroyante counter at 9, minute counter at 3 and no seconds subdial, plus a rattrapante button integrated in the crown instead of the usual position at either 8 or 10 o'clock. Would be surprised if Jaquet had gone to the trouble of designing two movements like that.
3. Jaquet started out with a V7750 ebauche and developed it into a two column-wheel rattrapante foudroyante. This may sound strange since the V7750 is not a column wheel movement to begin with, but the story goes that Mr Jaquet knows the V7750 like the back of his hand, which makes this the ideal basis for him when developing and adding additional chronograph complications.
4. The rotor in the pictures looks suspiciously like a V7750 rotor.
5. It's a 1/8sec foudroyante which points to a 4Hz beat frequency, like the V7750.
6. Anthony reports that the start/stop and reset button need hard work whereas the rattrapante button does not. I have exactly the same experience with my Graham and GP. (In fact, I'd definitely like a bit more pushback on the rattrapante button. It sticks out most since it sits on top of the crown and engages often accidentally.)
7. And so on.

So I'll bet my GP on the fact that this is the same movement (I wouldn't risk my Graham even on a sure bet).

Incidentally, I understand that GP did improve on the G1695 by asking Mr Jaquet to build in a disconnect between the two barrel springs when the chronograph is not engaged. So my question is: did this improvement finds its way into the Radiomir? And/or where any other improvements made?

Additional info would be very much appreciated! Wonderful watch, I'm tempted to add this to my collection despite already owning two versions of this movement! (GP anybody? )
