Hi!

I can’t find how to separate the dial from the movement on Longiness 6922. The border doesn’t have screws and I couldn’t find screws on the main plate.

Any one can help?

Dial feet location points or case screw holes ?. Cut locking screws under the bridges ?

did you know a very long time ago dials didn't have screws to hold them in. The dial flood came up into the plate and a tapered pin was shoved in a hole in the foot. Often times a pain to get out and sometimes had to be replaced as are in really bad condition. Then the miracle of dial screws but not all dials have screws. Modern dials have other things like this watch.

sometimes if you have the service bulletin or even the parts listing get a clue bike the PDF attached which was found at the link below

then an image your image notice I circled something I wonder what that is? I did manage to find you an image it really sucks but on the sides the things that I circled in your image you'll notice a little not she push on the notch it's a pivoted lever basically it will slide out or you can read the description of the pictures civet sounds better than what I'm saying they case the thing as to rotate worst case you can't figure it out just take the watch apart with the dial in place you'll see them once you see how they work the really easy. There are very common method on modern watches so they don't have to have screws are a lot simpler to make

Great  information John 

Posted

In addition to the information supplied by john, Dials can be and are fitted in all manner of ways. The simplist being the cheaper quartz watches which just push into plastic inserts, They may be screwed in via small screws set in the sides of the watch which hold the feet or from the top, these being eccentric and having a flange which cuts into the foot therefore holding them in place. Another is the one described by john which has a small pivoted clip that you have to pivot to remove the foot and the older pinned ones mainly on pocket watches which can be a real pain to remove at times. It is probably easier to look at the Ranfft site for a picture of th watch  than start poking and levering as the possibilities of breaking something are great.

Yes, I saw this paper but couldn’t id the bolts. I look for again

the problem is you're looking for a bolt let's see what the Internet says a bolt is so you can see a bolt is another name for screw except that's not what you're looking for you're never going to see this picture is really clear and the thing that I circled is really clear but you're still looking for something that looks like a screw and that means you're never going to find it.

now I snipped out another image for you from your picture. Look at your pictures you have two of them out a snipped out the other one. The other two mystery items don't you what are they? Now in the image I snipped out below I have an arrow pointing at something all you have to do is wish right where they arrow is and you release your dial flight you'll need to do it on the other side. If you don't believe may just take the plates apart you'll build the see them much better you take the plates off still definitely be visible.

then they're not always push type like this some of me have to pull out but with the picture I gave before it clearly shows pushing not unscrewing the bolt.

okay I had another thought let's go to the tech sheet notice the parts cross reference we know the part is called a dial bolt so let's see what it is and will get a part number. according to the parts reference it should be part number 934. Then if you look at the pictures we see 934 which looks really weird doesn't it? As you see it does not match the description of the dictionary of what a bolt is at all other than it's used to hold the dial on. So it is a fastening device it just isn't a circular thing with threats. It snaps on a post in the center which you can see in the picture  below and it rotates if you push on it. One direction pushes and releases the other direction pushes and holds.

But if still confused just take the watch a part it should become very obvious one holds the dial on

Yes. For those looking for a quick answer. Those “bolts” are located in two positions around the main plate. All I had to do was push them by one side and it turns realising the dial.

    • Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with. I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements.  Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!
    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.    
    • Use a Portwest Howie lab coat. They are the biological type so they have tapped cuffs so you don't end up getting the loose cuffs of normal lab coats catching everything. 
    • Some of the Chinese tools ae great and can be purchased at a fraction of the price of Swiss ones, some are complete garbage and some I'm convinced are coming out the same factory as the branded ones.
