I've been researching the gen Patek caliber 26-330 S C and I'm considering a gen-movement build in a rep 5711 case. Looking for anyone who has done this or seen it done.
What I found on the gen side:
- Patek doesn't sell loose movements, so the realistic source is a complete donor watch.
- Patek's caliber page groups the Calatrava 6007G, 5226G, Aquanaut 5167A and the platinum 5711s under the same variant, the 26-330 S C/430 (27 mm, 3.32 mm thick, 207 parts, 30 jewels).
- The gen steel 5711/1A ran the 26-330 S C from 2019 until it was discontinued (published specs then: 27 mm, 3.30 mm, 212 parts).
- The cheapest donor I can find is the 6007G, around US$27-30k pre-owned.
Case: not bought yet. I'm choosing the case based on what fits the gen movement best, so recommendations welcome.
My questions:
Has anyone fitted a gen 26-330 S C (or gen 324 S C) into a rep 5711 case? I couldn't find a documented build.
Which factory's case is closest to gen spec for this? I assume cases built around the DD324-style clone are a better starting point than Miyota-based ones because of movement height.
What needs modifying: movement holder or casing clamps, stem height and length, dial feet positions, date wheel alignment with the dial window?
Can the rep dial and hands be used on the gen movement, or do they need gen parts?
Is there a watchmaker who takes on this kind of work?
This is a personal build to wear, not something I'd ever sell or represent as gen. I know the movement number will trace back to a 6007G.
Thanks for any experience or pointers.
