Okay, so I am still confused here.  You are saying that if I am not comfortable removing the shock spring from the Seiko, then turn the balance wheel assembly over, and move the wheel out of the way stretching the spring (gently)?  The problem that I am seeing is that it sure doesn't leave a whole lot of room to get the oilier between the coils of the balance wheel springs so I can get it to the hole for the pivot.  Maybe I am being too cautious of how far I stretch the spring.

It can be done this way but it is risky . I often do this to adjust for beat error, as that can be a trial and error process to get it somewhere near. Removing the balance from the cock will simplify things and give you room if you wanted to oil from underneath. Personally i  always want to disassemble the jewel setting to make sure everything was clean in there. That does come with practice though as is something you would want to work towards

Okay... well I will need to find some scrap Seiko movements then as all I have currently are the ones that are in my watches that I wear.

So completely detach the hair spring from balance wheel and cock?

No the balance which would be the staff the balance wheel and the hairspring inc. Its attached components. You are just releasing the stud from cock to do this

Hello everyone, I came across this tutorial while looking on the net for parts for an NH36. I'm just an amateur and rather a beginner (and French. Forgive me my English) but my level today allows me to disassemble / reassemble a movement, clean it, oil it, and finally adjust it. I mainly work on NH36, ETA 2836 and Miyota 8200 (watch mod). My first attempts with these small parts were catastrophic, losing them most of the time! Also not having tons of money to buy tons of expensive tools, I make them as much as possible. Specifically for these parts, I made a small box out of plexigass to avoid losing them if they jump out and a small tool which makes the operation incredibly easy in few secondes without loosing spring. If it can help newbies like me, I would appreciate it.

I can't post video here.

If you want, give me your email on MP and I will send you a little video I made this morning for you.

 If you can post on you tube, give us the link to your vid so we  can all see the mess you made. lol.

Hope this  is just to show how to use the tool and box,  but you don't really remove shock springs with balance attached to the cock, do you? 

Seperate the balance so it wont get damaged in case hand slips. 

Slip proof approach.

What is wrong with removing a non captive spring on a Seiko balance whilst in situ? Probably safer to remove the cap on the mainplate first, so you don't damage the staffs or caps by putting too much pressure on the pegwood tool. Here's video of how easy it is.

Hi Jon, 

The vid didn't open for lack of fast vpn on my device.

The oscilator is in harms way as shown in flannel picture, one slip of hand  and he needs a new replacement. 

I detach the oscilator from the cock so it isn't there to get damaged and when seperated I have a chance to give a good clean.

Maybe I have misunderstood something, why would you remove the balance complete to clean and oil a cap jewel?

 

Tom

Are you guys putting me on? 

I am not saying  that seperating balance complete and cock facilitates removal of cap stones, rather if flannel77  seperates and keep the balance complete out of harms way ( say in a box)  he  can't damage the it in case  his pegging tool slips , because the balance is  not there to get damaged, its far away from the crime secene safe  in a box.

Pegging tool, screw drivers can slip as flannel77 shows, thus easily damage the balance.

Hello everyone, I'm not sure I translate what you write correctly. I made a video which is not famous because I don't really have what it takes. From there my message took a little time to be validated by a Moderator and I haven't come back here since.

So, I do exactly the same way as on the video that was posted with just in addition my little "anti-loss" plexiglass box that I use as soon as I fear that a part could jump in a distant galaxy ! 🙂

Contrary to the photos which were only there to show the "principle", obviously I temporarily fix the movement holder to the table with rodico so that it does not move otherwise nothing can be done of course !

All this works perfectly for me in complete safety and without risk of loss. Exactly as on the video, I perform this operation when the movement is completely disassembled.

If I understand correctly, I believe that when you touch a movement there will always be a risk of damaging it, even for an excellent watchmaker, right ? The risk becomes smaller and smaller the better you get, but it will always exist, in my opinion. When I was a complete beginner and wanted to learn, I broke a few, lost parts, and I knew the risk was great. But that's also how I learned from my mistakes and it hasn't happened to me for a while now, even if the risk is still there !

 

Besides, I watched hundreds of videos on youtube to learn and I've never seen a watchmaker do anything differently or anything other than what I do or what the video shows.

Am I missing something?

No i don't think you are Flannel, it was a very good post you made and a good added tip with the plexiglass to prevent loss 👍.  Basic ideas and techniques are all we should really need, i dont feel the need to have from a post or provide to a post every little detail. We are not small children that need to be spoon fed, the rest we should be able to figure out for ourselves by trying the technique ourselves and honing the details ourselves. You crack on Flannel and keep posting ideas.

Hi All, 

in my first attempt of lubricating the jewels and lowering down agin the spring, i mess it up. The spring literally disappeared, I'm not sure where wanted to fly :).
Where i can source this diafix from? Anyone can help is super much appreciated. Thanks

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      This makes much more sense now, the oil is withdrawing itself to make as little contact with the epilame as possible. Same principle as wax on a car creates a hyrophobic surface that makes the cohesive properties of water molecules pull together.  The water beads run off only when under the influence of gravity but still remain cohesively beaded up. And as mentioned earlier a pivot would keep the oil in place on a cap jewel.  Epilame on an escapement would be a different scenario, there is nothing to hold the oil in position if gravity tugs at the bead to move, plus the escape teeth pull the oil about Maybe this is why its suggested to run the watch for a short while to remove the epilame to make two oleophobic surfaces either side of the oil, creating a ring of fire 🔥 around it 😅

      Balance wheelwheel crooked

      By mikepilk · Posted

      As with every skill it watchmaking, it takes practice. Notice at the top of the document it says, "Practical work - 40 hours".  I can get the balance wheels 'close enough' to flat, but never seem to get them perfect. Same with gear wheels. Guess I need more practice.

      Beat adjustment

      By transporter · Posted

      Has it got a beat adjustment on the platform or is it a fixed hairspring? in short what you are looking at to get it just about in beat is to get the roller jewel sitting dead centre between the banking pins. So remove the platform and take of the pallet fork and escape wheel to give you clear line of site, sit the platform with the balance in place and with it level look between the banking pins and see if the roller jewel is sitting between them, if it is nice and central its there or there abouts in beat, if its not the the position of the pinned end of the hairspring needs to be adjusted to move the roller jewel into the correct position, thats why I asked if it has an adjustment on the platform or not, if it has its an easier job.

      Help - London Elliott Mantle Clock Night Silence

      By MapleWood · Posted

      I've managed to adjust it. I'm going to try and explain it as well as I can with my limited horology knowledge but I hope it helps someone in the future. There is a cam to the right of the front plate as shown in the picture. As the clock ticks along, the pin indicated in the gear comes around and slots into one of the silencer cam gaps, turning the cam. The pin completes a full rotation in 2 hours. To adjust the cam to start at the right time set the clock to just before 7. I did 6:45. Then I turned the silencer cam anticlockwise, which spins freely, until it pushed the silencer lever up and was placed just before the drop. Just before the 7AM indicated in the picture. All I then had to do was progress the hands to 7-7:15which made the pin slot into the silencer cam gap and turn the cam so the lever comes down again, unsilencing the clock. That was it. If anyone comes across this issue again I'd be happy to assist. Thanks again to everyone that helped. Hey Transporter! Thanks a lot for the reply. That was a really good explanation and I'm sure it would have made my troubleshooting a lot less painful haha. I'm sure someone will find it useful in the future. Thank you again for taking the time to try and help me out with this.

      Epilame / Fixodrop

      By Waggy · Posted

      Now I'm completely confused, it would appear that the epilame  is oleophobic  as @Marc states: This oleophobic  behavior can be seen as beading of the droplet (as above) which stops the oil spreading which is supported by what we observe on treated/untreated cap stones (for example), but as @VWatchie states this should make the drops more mobile and is supported by the literature:   A review on control of droplet motion based on wettability modulation principles design strategies recent progress and applications.pdf   However the whole point is that we have less mobile oil so an oleophobic  would see to be the opposite of what we want. In fact this beading and high mobility are desirable properties in things like smart phone covers, see below.  I am fairly sure that epilame doesn't make the droplets more mobile, so maybe its a strange coating with dual properties that are both oleophobic (beading) and cohesive/adhesive resulting in low mobility?? This may explain the high price??
