Got this interesting guy off eBay as a non-runner. It was fully wound to the point that I couldn't even disengage the click to let down the mainspring. I noticed the balance turned, but not easily, like it was glued in place.

Not wanting to force anything, I took it off, then noted the pallet fork snapped back and forth briskly, so I knew there was power through the train. Took off the balance jewels, and found out they were stuck together with goo, both top and bottom. You may have seen the photo in the "Stuck cap jewel" thread. It must have sat in a drawer for a reaaaaaaaaaally long time for the oil to turn to shellac like that.

I got the dried gunk off, put the jewels back in, and it sprung to life! What a fun feeling. It still needs a full service, and the hairspring looks a little suspect, but we're off to a good start.

I really love the face and case, even though it's a little small on my wrist. The movement is really slim, too. I dig it.

Ready for cleaning. Such a nice, simple movement.

Oh super cool, thanks for finding that! I was wondering if it was designed to be a ladies' watch, since it's a little small. Either way, I wouldn't hesitate to wear it.

Got it cleaned up and back together! Did a preliminary run on the timegrapher after about 15 minutes after a full wind. I know amplitude is low, but I'm going to wear it around for a bit and see how it changes after a few days, then decide what to do with it. Maybe start by sourcing a new mainspring.

Gotta say, I'm pretty happy with the results. I paid a little more than I probably could have, but for something listed as a non-runner, it's not so bad.

I polished the original crystal, and of course didn't notice I put it back with the most noticeable scratch right at 12 o'clock...

Love the dial.

Unfortunately pics not showing yet, so don't know what the amplitude is. The amplitude will usually go up after a days running - you can see an extra 20° . Did you use 9415 on the pallet jewels?

I wouldn't bother with a new mainspring, apart from (maybe) not being exactly flat, it looks excellent. You could buy a new one that doesn't look that good.

My first step with low amplitude, is reclean and oil the balance cap jewels.

Is there any excessive play in the barrel arbor bushing in the bridge?

Well that's strange. They were there when I made the post last night, but now they're all broken. I also can't go back and edit any of my posts for some reason. Hope I didn't break any rules. I'll try attaching them to this post again.

I just tried uploading the images again and got an "unknown server error." I'll have to try again later. In the meantime, I've made an Imgur album here with the images.

Last night, amplitude was 256 dial up, 233 dial down last night. This morning it's 264 and 268, respectively. Beat error of 0.1, and losing less than a second a day. Really shows what a difference letting it run for a while after servicing makes.

I actually don't have 9415 yet, and have been using 9010 on the jewel faces. I've read that it's the best alternative.

No, there was barely any side shake at all. I even remembered to check it this time 😉

Those are excellent numbers - to get DD/DU so close shows you have got the balance pivots and jewels nice and clean !

9010 is fine on 18000/h pallet jewels - best to be sparing with it, as it can spread around.

    • 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.
