Panerai OP III / Valjoux 7750-P1 Alternative

[lupo]

Hi,

by pure coincidence, I got my hands on a heavy water damaged pam107 with the OP III caliber.
Had a quick look and it seems the watch stood still for many, many years without anyone caring to restore it.
From what I can tell, I would need to replace at least half of the movement.

The idea is to replace the whole thing. I did try to locate a Valjoux 7750-P1, as the OP III is based on this, but it seems these are super rare.
Spoke to my watchmaker already, who mentioned a sellita alternative, but was not able to find it in the documents he has on hand.

Can any of you give advice where to look?

thx.

Ali express and search for 7750 movement

I am talking about a genuine watch. And I am looking for a gen-swiss 7750-p1 (non-chronograph) movement. I am afraid Ali will not be the right place.

Just do a search on ebay for

guys, I did try everything. it is easy to get a 77xx chronograph., but I am after the NON CHRONOGRAPH version of the movement, it is super rare. Valjoux 7750-P1 is a movement where the whole chrono module is missing. I will just order parts separately and replace the whole thing. I did manage to clean half way good the damaged plates. Let's hope the watch will live again.
I may even be able to send the movement plates for rhodium plating, once tested for function. Will be expensive, will take ages...

My watchsmith did the conversion once for a franken pam 64

Sure. Not hard to remove the module. I ordered a bunch of internals (parts are quite common for this movement) and will do the assembly soon. I hope it lives again.
