Differences between OPxxxiv, P900, and Baumatic movements

Since researching the new 42mm submersibles, I noticed there seems to be a bit of hate for the OPXXXIV movement, mainly because it is the same base movement as the Baumatic, which is available at a much lower price. However, just wondering if someone could enlighten me as to the specific modifications that Panerai have made to the movement? The Baumatic has a different jewel count and power reserve.

Also, I noticed in the Due models they are swapping out the xxxiv for the new fully in-house P900. The P900 seems to have identical specs to the OPxxxiv... have panerai just started making the OPxxxiv in-house to avoid the backlash?

Makes me wonder if I should have held off ordering a 683 if the submersibles are going to follow suit with the p900...

Thanks
Matt

dunno about the dues but the P9010 in-house was used in the 42mm submersible PAM682 (the last iteration before they tweaked the dial and removed “luminor” from the submersibles).

as to practical difference, the 9010 has a jumping hour setting function which is really nice to have.

Yeh bit of a bugger that they went away from the 9010. But having tried on both, I must admit I prefer the thinner profile of the newer versions which the thinner VL movement allows.

I think while pam 9010 have quickset hour,the Richemont movt have quickset date

Personally I do appreciate quickset hour more than quickset date,but probably people have different preferences

Currently I’m travelling with my non quickset hour JLC and I just realize how I miss the quickset hour,especially during DST change in Europe

One thing that intrigues me is the increase to 25 jewels in the OPxxxiv, as opposed to 21 in the baumatic.

Anyone have any idea what the extra jewels are doing in the pam movement?

Probably they rework the geartrain to change the central second to small second? However with my simple logic it’ll only take 2 extra gears and probably 2 extra jewels,not 3

I think you are likely spot on mate. Looking at the pic in post 2, while the description says 25 jewels, the back of the movement in the pic says 23.

why panerai changed it from 5 days power reserve to 3 days? just to make the movement thinner?

I remember reading that panerai changed the innovarive materials (silicon hairpin I think) used in some of the core components of the Baumatic to more traditional types - which resulted in a reduced power reserve and loss of antimagnetic properties. I've been trying to find the specifics but can't find the article I read.
