My Panerai, PAM00088 is based on Valjoux 7750-P1. Can’t remember the exact year of mine, but about 2004 I think.
The watch Kryton is looking at contains the OPIII movement I think, OP being the outsourced movement designation. This also based on the Valjoux 7750.
Panerai’s in-house movements are shared between other brands within the group. IWC, Cartier, Baume & Mercier. I think where Panerai have gotten in trouble is when they have described their watches as having in-house movements but in fact had an ETA. I love my Panerai, I’m happy with the movement. When I wear mine I’m never worrying that it’s a Valjoux, equally when I wear my Rolex I’m not thinking about the movement. I get why people do, just not me.
Would I buy a Panerai new at RRP? Nope. Will Kryton’s £3600 Panerai hold its value? I would suggest so.
(I’m on my second Panerai, well aware of the movements….i may be gullible in that regard! Both of mine bought for a price I was very happy with. My last Panerai I managed to part ex a watch that I was struggling to sell, so for me it was a very good deal)
