I think if I’d had the option to buy a fully working caliber 240 I would never have started this project. Part of the journey was taking something that barely had any value as parts and transforming it into something else.
That being said, taking a caliber 240 from a cheaper model and transplanting it would have spared me a lot of stress. The only issue is the finishing and engraving is different.
This link goes through the differences pretty well:

The difference in finishing is very visible on macros. The reason is that the high end pieces are made by their master watchmakers. It's therefore no surprise, but it's kind of disappointing, when you look at what the independents (fx F. P. Journe) or A. Lange & S are doing at a lower price point than Patek.
It's off course caused by a higher annual prodution number, so they focus on the quantity, than quality on the lower price range pieces. It's an explanation, but not an excuse. They should be able to uphold the level of quality even though they increase the production numbers, but don't to keep the profit margins up.
Historically they went away from the Geneva seal and created the Patek seal, and market this move as the Patek seal means higher quality on their movements than required by the Geneva seal. But in reality it's on the contrary regarding the timepieces that are not grand complications or rare handcrafts.

jptrosch have you guys already found a solution for the pusher / corrector situation with the midcase?
My watchmaker is looking into ordering some generic correctors that look and act the part from one of the aftermarket parts suppliers. A fellow forum member actually pointed them out to me on cousinsUK but they were out of the correct size. At this point it's just a matter of time. None of the issues that remain are anywhere near as problematic as the ones we've managed to solve.

Not much to report from the past week. We had to replace the setting pinion and opted to go with aftermarket correctors for the case. Here are some more photos and also a link to a breakdown of the dial side complications of the cal. 240 moonphase power reserve.

Nothing new to report. I haven’t heard from my watchmaker in several weeks. He tends to work on a project for a few weeks and then puts it aside to work on another project for a few weeks, so I don’t imagine anything’s changed.

jptrosch I would LOVE to refinish the case, bezel and bracelet for you on this unique project.
I’ve seen your work man, that would be awesome.
It’s gonna depend on how finicky the keyless works are. The last thing I want is to remove the stem to take the movement out of the case and have to reset the keyless works when it won’t go back in.
