Refitting and setting Pallet Stone

Thanks for this video.Isaac

That pcb idea is genius. Thank you

So I tried disassembling a movement (Miyota 8200a) for the first time yesterday and when I was putting it back together I noticed that one of the stones had partially came out. All I had was a basic set of watch repair tools off of Amazon so I had to make a homebrew version of the metal plate shown at 0:34 to reset the stone. I took a washer, used a sharpening stone to flatten the surface and used an engraver to make a tiny hole for the shaft of the pallet fork. I then placed the pallet fork on it and carefully used a pair of tweezers to push the stone back in place. Afterwards I used a hot air rework station on the lowest air flow setting while holding down the pallet fork to reheat the Shellac. The watch still works but man that was stressful. Anyways I couldn't have done it without this video.

Really glad this video was helpful! Yes, it's a stressful job. The one upside is that if things go wrong, you can try again; shellac isn't permanent.

amazing work! Congrats!😲😲😲

Hi. Remarkable. I discovered the soldering iron technique 2 weeks ago too while on an echappemetre.. And there you also use it.

I love your videos soooo much

[@nifty3000]

What are the guides that you talked about? The ones you put on the screen?

[@sonik954]

Curious as well?

Thanks for this, Stefan! I just found your channel and subbed. Cool idea using the circuit board (no pun intended). Have you tried something like a wet rag to reduce heat transfer? How did the repair work out? Did the timegrapher show reasonable beat error? I messed up a pallet on a practice movement - forgot to avoid IPA and the jewels moved.

[@sma1968]

Thanks! I think the biggest issue with using water or the like to cool is the tiny size... consider that a drop of water would be about the size of one of those jewels... haha. I don't think it could really absorb and eliminate heat too well. Final result turned out nicely - had to adjust the pallet stones a couple times, but did get the perfect depthing after a few tries. yeah, IPA will force you to learn how to shellac a jewel. lol

@@sma1968 I recently messed up on a junk practice watch and forgot not to put a pallet in IPA. Although it was only in for a couple of minutes, the stones moved. Might see if I can reset them

[@watchrepairworld1203]

How are you Stephen, I wonder is the microscope is auto focus or the camera , as I see you magnify the picture or minimise with no bluring , please answer me

[@sma1968]

the microscope is "par focal" which means that it will stay in focus as you zoom in and out. No autofocus.
