Franken Patek 5712 Project

[jptrosch]

Wow, incredible update. Do you know which pushers he landed on? This has been a looooong journey.

No I didn't ask. I don't think they were the ones on cousinsuk from the sound of it. That's an understatement, I think we're coming up on three years now.

beautiful..

Shoutout to @Riverwind85 for sending me a link to the gen pushers on eBay for less than half of what they would have otherwise cost. They look like they might be white gold, and they come with a nautilus crown from the white gold 5712. I'll make a decision at some point about whether to just use that crown or go with steel.

My watchmaker was planning to cut the case for the pushers next week, so as soon as the pushers arrive he's going to start milling.

If anyone's curious about the breakdown of rep vs. gen parts at this point - it's all gen except for the case, dial-side crystal, and bracelet.

I bought a gen dial-side crystal but it doesn't fit the PF case. I went with a PF case because both the PPF and 3KF are actually too thin. The 5712 is already a little bit thicker than the 5711, and we wanted to have some wiggle room because we didn't know how well the movement was going to fit into the case. The bracelet is PPF though.

look forward to seeing the final product but as of right now incredible work

Update: The slots for the pushers have been cut. I haven't had a chance to touch base with my watchmaker since he let me know, but to my knowledge all that's left is to reshape and polish the case back.

Oh boy.

I'm interested in why the pusher recesses are slits like that, instead of just holes for the pushers. Is it because the pushers don't reach all the way to the movement?

Yeah, I want to say the slits accommodate the space for levers which the pushers activate

The pushers have been installed. You can see the levers that the pushers hit to activate the mechanism.

Stunning progress!
Good luck for the final steps.
Seems like a long journey will come to an end any minute now.

The caseback has been shaped and the case assembled, might still do some touching up - almost there.

All that's left is timing and fitting the crystals. It'll sit dial-side down overnight tonight and then dial-side up tomorrow. Then it will be run all the way down. After that, it's done. My watchmaker and I agreed that at some point in the future we're going to replace the case. The PF case just isn't up to snuff in terms of the quality of both the steel and the milling.

What will you replace it with?

What will you replace it with?

I’m probably going to try with a PPF case, but even after correcting the bezel and crown the construction quality may not be substantially better. What he ideally wants to do is scan a better constructed case to create a CNC copy in better steel.
