I can understand what you say, but why are you using Spanish in an English forum?

I have used the dial foot machine with good results , but it takes practice and cleanliness to get the best results . To be honest ,...although I love tools , I don't think that the number of times I have actually used the machine merits the cost .

Like most tools:)

somewhere in the 500 project que is a dial foot repair.   I've been thinking of how to hobble together a resistance solderer (the key is low voltage, like 1.5, then it should be able to solder copper).  I made a spot welder once by wrapping thick speaker wire around a old sodium light ballast so would probably go along those lines; cheap and lots of current available.

Thinking more about it, the strength of soft solder is around 5000 psi.   Two part epoxies are something like 1000-2000 so are weaker.  However 1 part thermal set epoxies can get to 5000 psi - if the stuff sticks, it should be easier, and less risk.  

Has anyone tried the 1 part heat cure epoxies?  You have take them to around 120C I believe - any issue with lacquer or other finishes at those temps?

I'll copy transfer the points with my "dial feet position gauge" to a sheet of paper and measure the distances and angles. Then I 3D print  simple dial holder which I use to transfer the correct positions.

Hello to all. My post is all about the situation when I have to reattach a watch dial to the movement, but when the original watch dial feet are broken or, in this case, missing. 

I have added sticky pads, and tried to put it all back together. However, there is just not a tight enough fit of watch dial to movement. And this means I cannot properly reattach the hands as there is less space on the dial. 

I tried pressing them together more, but also no good. And I don't want to handle the dial too much with or without finger cots. 

WHY won't the sticky pads stick properly? 

Is it possible I have, inadvertently, bent the watch dial? It is only a small cheap one, but even so I hope I didn't. 

What to do that I haven't done already? 

Sorry the photos are in a strange order, but it wasn't easy uploading them. I think you can see what you need to.

Hi  The answer to your problem is to use dial dots these are small foam double sided dots which you stick to thr front plate and then re attach the dial carefully lining up the center hole before pressing the dial home firmly.

The dial feet can be resolderd on using a dial foot machine or a small jig to hold the wire. If done correctly no harm comes to the dial this of course is cot possible with dials with plastic faces and watches with calendar works as they foul up.

If you wish to you can PMessage  me with your address ( If in the UK) and I will post some dots to you.  They are available from most parts suppliers.    Cheers

Hi and thanks for the reply. 

Are the sticky pads I'm using no good? 

Is there something I can get from, for example, Cousins UK? 

The ones I have are like this :-

Hi W they look a tad too big. The dots are made specificaly for the job of retro fitting watch movements, I have used them without any problems. The watch you are working on looks like a Miyota 2030/35, I have used them on this type of movement ok. make sure the dial and front plate are clean and free from oil, a wipe down with Isopropyl alchohol and when dry try again. The offer still stands I have a few sheets. If you only need a few .

Thank you very much for your advice and the offer. I am not often in the UK these days, so I wouldn't be able to pick them up so soon. I see Cousins have some, as do ebay. 

But do you have some advice on how to NOT break the copper dial feet when taking the movement off the dial in times when you need to? Obviously they are good things to keep on, but are not made for pulling, bending etc.

Hi  W  removing the dial without breaking the feet off takes care . there are differnt ways the dial is fitted, some use small screws on the edge of the movement which must be loosend prior to removing the dial, and some mainly quartz with plastic frames are just friction fit, the method of removal remains the same. Withe the dial loosend if screwed insert a screwdriver between front plate and dial and twist a small amount then do the same at the other dial foot, continue like this untill you can grasp the dial in your fingers and lift straight up from the movement avoid twisting .   all the best

To be honest I don’t like dial dots, they seem a bit squiggly to me, 

i never really liked the idea of tape under a watch dial .

These are feet not dots, epoxy glue not tape. But I suppose they may not fit if overall tolerances are tight.

Hi  as jdm remarked they dont fit all, watches with calender work can be a problem due to clearance and I have seen in order for the dial to fit correctly the front plate sometimes has to be reduced to allow for the extra metal on the foot, Its a case of try it if it fits its a bonus if not do whats required to get the fit you require.

Given how delicate dials are, are there any potential issues when dial dots or tape are used to stick a dial to a movement when there are dial feet going into the movement?  I want to make sure that removing a dial stuck on by tape or dots doesn't require twisting or tilting the dial away from the movement when it comes time to service it.

While I'm at it, do ETA dial spacers hold onto the movements at all or are they loose?  The option to dial dots I am considering would be using shellac to temporarily glue the dial to the spacer.

Why am I worried about attaching the dial when there are feet?  The holes in the movement do not have clamps, and I gather that best practice for longevity of the watch is to have the dial attached to the movement.  Thanks for any feedback on this!

    • One of the problems with trying to Photograph Phils things are that his enjoyment was building these things so they tended to E falls on what will see if I can find some earlier pictures or any pictures I wasn't even sure because I was looking for that specific picture for somebody else and even it got the last version and that would have been the last version. You will note that he put the indexing on something that he could unscrew it or whatever and it can slide back out of the way so the rest of the lathe can be used as a lathe. With the lathe cut are actually coming down from the top I was there once where he demonstrated how to cut a pivot with the setup it was really beautiful. Older set up if I remember it's not a worm gear assembly in the thing in between the stepping motor and the holding block I believe this particular one was like a 100 to 1 gear ratio. Earlier version with watchmaker's lathe. Even looks like he is the watchmakers bed and then switch to something he made. Then I do have other pictures and things of the rotary stage in use. In the raw so if you tube videos here is an example of one were somebody's mounting a three jaw chuck. At one time there were available on eBay they were not cheap but if you're patient like I was I found one cheap on eBay. After you watch the video it look at his other videos he is a whole bunch of other examples of the same rotary stage. That I do know there are other pictures examples and possibly videos you just have to track them down. One of the minor issues of finding this particular tech sheet for the unit is I believe it was a custom manufacturer and the company change their name but I remember the new name here's a link to the company https://www.ondrivesus.com/rino-mechanical-components                
    • Escapement adjusting always interesting and depending upon the reference always confusing. Okay maybe it's not always confusing but it does lead to confusion. I have a PDF below it's actually a whole bunch of separate stuff including a hand out that came from a lecture that's on you tube. Then from that we get this image Consequences of doing things especially if you do things out of order or you do things for the wrong reason. Oh and even if the watches working I made the mistake one so showing my boss how tweaking the banking pins on a full plate on the timing machine made the amplitude get better and now he thinks that's what they're for and I don't think a fully grasped exactly what horn clearance means. Consequence of doing things. Notice what it says about opening and closing the banking pins and total lock? So yes I've had that on a full plate where it won't unlock at all and that's the banking pins or a combination of things basically. So banking pins unfortunately get moved. One of the ways to tell if it's been moved is the look straight down at the end of the fork with the balance wheel removed. Power on the fork push at the one side look at it push it to the other side also look at it and compare anything with the center reference the balance jewel and see if both sides of the same. No guarantee after the same there in the right place but at least are the same typically when people play with things one side will be way off from the other because they had no idea what they were doing at all because of course it's a full plate and you really have to paying attention and even then there's still hard to do. Then the other thing that comes up like it shows below is people often adjust the banking pins to do all those other things as opposed to horn clearance which is all that it's therefore and maybe bonus Guard pin clearance although you're supposed to deal with the guard pin is a separate thing like single roller gets bent in Or out or sometimes physically gets moved in and out. Some full plates older escapement's typically pallet forks held together with screws and you can actually unscrew and move the entire assembly in Or out more complications to deal with.     Escapement handout wostep nscc.pdf
    • If he was much younger and some sort of sports player it wouldn't be a problem. They would be in there and doing surgery and he'd be back on the field in no time. Unfortunately when you get older little things are bad and big things can be really bad so not good at all.
    • Where I work everything incoming watches whatever detailed descriptions are taken entered into a computer program and photograph of each item. Then ideally although it depends on who's doing the paperwork detailed descriptions can be quite good other times there lacking. Like I really like it with pocket watches if they would record the serial number it avoids confusion later on. Then when watch repairs are completed that is also entered in. It's one of the amusements I learned when I was in school instructor had a shop and commented about the important aspect of keeping detailed records of repairs. Because oftentimes a customer who got a new crystal will come back later on when the watch doesn't work and expect you to fix the entire watch for free. Then you can remind them that they just got a crystal. Strangely enough that keeps coming up or occasionally comes up where I work now. One of the problems of using the service marks on the case is that in the case of pocket watches oftentimes that's not the original case. Then case marks? What I was doing warranty work for a company I used to describe a code number in the back of the case and it would tell me the next time I see the watch that basically what I did I made no attempt at keeping track of customers because we had literally thousands of them I think they sold 30,000 of these watches and they would come back by the hundreds because they had a lifetime warranty. Yes that's a story all of itself but I would put a code number that would reference what was done to the watch the last time and think I had a date in there somehow so it did tell a story if you knew the code. Another shop I once worked out the number would reference the page in the book. So other than knowing we had been in there you would have no idea what happened because you have to go look at the page in the book to see what happened. Then the problem of how you examine a watch you should examine the watch in detail every single time to avoid complications. Although on vintage watches and this is a of amusement I have at work when people ask something and I say of the watches done when it leaves. This is because on vintage oftentimes problems won't show up until the watches much farther into the repair like it's now running and you discover things that you can't discover before because it wasn't running to discover them that also become sometimes difficult to have exact rigid prices are estimates of repairs or in the case of a pocket watch you may not find out if a casing problem to later on when you case it up in the watches running. I was just thinking for all those people that would like to leave a mark maybe you should learn to do what some of the past watchmakers did? Leave a mark but leave it in such a way that no one will ever find it? Typically not done for repair purposes but done for other reasons like identifying it's legit. I have a friend with a Gruen watch and one of the Roman numbers the bottom line that just looks like a line under extreme magnification actually says Gruen watch company or something equivalent. So here's a link showing how to mark your watch without being seen although that's not the actual title. So if you can learn micro engraving you can engrave the watch someplace probably just about any place you just have to remember where you put it. https://cnaluxury.channelnewsasia.com/obsessions/how-to-prove-if-watches-are-authentic-secret-signatures-182516  
    • I have acquired a Citizen Leopard 36000 watch. My reason for purchasing it was my desire to own a timepiece with a 36,000 BPH movement, and the price was reasonable. Another motivating factor was gaining hands-on experience with the mechanism. The watch is in good condition, but I intend to fully disassemble it for maintenance. First and foremost, if anyone has prior experience with this particular model, I would greatly appreciate their insights. I do not have access to Citizen’s specialized lubricants and will need to use the ones available to me, such as 9010, 8000, and 8300 grease. Additionally, I do not possess the appropriate oil for the pallet jewels and will only be able to clean them.
