Hey,

I changed the crystal on a Seiko Ufo. Everything seemed straightforward.
Looks really great now.

Everything was well with the watch only the top button was jammed. I thought there might be some dirt but when I took it apart ist was all proper and cleaned.. maybe needs some grease. I did not put any.

Now I realize that the movement is jammed. Bummer. I did not do anything much that could bend the mechanism.. but still think it might be a possiblity.

Do you think I can take it out and test without casing? Can I still attach the crown only and check if it has to do with a spacer?

This document helped me alot to find all the parts:

 

Thank you.

It's always a good idea to post photos of the watch & movement you are talking about, to illustrate the problem you are having. This will help people to understand, and they will be more likely to offer help. It makes it easier and less tiresome for everyone. Also, it is worth making an effort to learn the correct terminology, and to use it when posting. Don't worry too much about it at this stage. It takes a while to pick up.

I didn't know what a Seiko UFO is, so I had to look it up. There seem to be a whole range of them. When you are talking about the jammed top button, do you mean the start/stop pusher on a chronograph version? The 7005 is not a chronograph movement, so it will be of limited use in identifying parts, if yours is a chronograph.

Yes, you can, and should, check the movement outside of the case. I'm not sure what you mean by your last question about the crown and a spacer.

There seems to be a common problem that the pushers can be stuck, so working but do not get out. I looked at the springs but they were fine, I was able to push the pushers also manually.

Think this watch would require a bit of professional servicing maybe lube or something I cannot do. The date did also not move correctly. Day moved well, Number is stuck.

I would be interested what a new movement or service would cost?
Also if someone can be interested even if it has some flaws to fix it or merge with another one from that time?

That balance wheel is distorted in the video. Look at that up and down oscillation. How was the time keeping? 

If the pushers slide without the movement in and the gaskets are not hard then the movement needs a service.

Also make sure there is no crud inside the pushers or around the case holes they sit in.

It definitely needs a service from someone who knows what they are doing. As Melt points out, the balance wheel is not true and needs to be straightened or replaced. The case and pushers will need cleaning and lubricating, as will the movement. The cause of the stuck date wheel will become clear when the movement is stripped. Other than that, it looks to be in good condition with a lot of potential. I would concentrate on getting a competent service. I don't see any need to swap the entire movement.

I found a handy pricelist from Seiko and will ask for a quote there now.

I doubt very much that Seiko AT will service your watch, reason given "no parts available", or "discontinued", or "we only work on the calibers specified in our price list". Let us know.

    • You shared this test with me a few months back on a Hamilton project and so I had checked this watch to find the pins were still equally spaced. Their screw slots were undamaged and very tight hard to move so maybe no one has messed with them before. I can't work on it much today but I did measure the fork slot again and it seems like 0.44 is the right size. I measure the jewel that had been installed at just 0.42. would an undersized too narrow impulse jewel impact the impulse drastically? I ask because I have had it at a state where flipping the fork manually with a tool would unlock some of the time, but the balance was never capable of unlocking.
    • This was what I was afraid of. The movement is not one of the generic black square modules. Remove the movement from the clock and try prying it open very carefully, without breaking the plastic tabs. The plastic might be brittle from age. Clean the wheels and check the battery contacts for corrosion. Check the PCB for bad solder joints. Take plenty of photos along the way.
    • 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.
