Hi all. I'm absolutely brand new to the world of mechanical watches, but have always been fascinated by the way they functioned. So, I took my first step into them, getting myself a cheap, crappy ebay mechanical watch with a chinese movement. I knew that by all accounts this would be a rubbish movement and mechanism, however I wanted something that I could take a look at without risking any sort of investment, gauge my interest in the hobby etc. However, after receiving it, one of my friends let me know that he had a near identical cheap watch that was broken, and offered me to have a look at it as practice. I agreed, and have spent the last few days doing research and taking it apart, before putting it back together again. I've managed to learn quite a lot from it, however I've found that when putting it back together again, the pole of the escape wheel that keeps it in place either end seems to be too short, as though something had broken off. This means the wheel is sat basically loose and wont reach the crystals at either side to keep it in place while it spins. I see no way to fix this, so i intended to get a new wheel to replace it with, however I can't find the name of this type of movement anywhere. It is the kind used in this: ( https://www.amazon.co.uk/Jechin-Skeleton-Hand-Wind-Leather-Mechanical/dp/B00VPRZC50/ref=asc_df_B00VPRZC50/?tag=googshopuk-21&linkCode=df0&hvadid=290896788181&hvpos=1o3&hvnetw=g&hvrand=13027367026987882679&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9047006&hvtargid=aud-545868369748:pla-468442151749&psc=1 ) . If I really wanted to I think I could just order one of the other watches that I've found that use this movement for £5-6, however I was hoping I might be able to keep to my strict student budget and get just the escape wheel somewhere. Does anyone know where I'd be able to find something like that?
p.s. Apologies for the lack of knowledge on the subject, I know I'll come across a bit new to the whole thing, but trying to learn as I go
Hmmm, kind of!
But........ It shows great potential as a hobbyist alternative, with some tweaking.
After a back and forth with @Andyhull on another thread it got me to thinking perhaps it's not as useless as my initial annoyance led me to think, (I broke a mainspring trying it but to be fair the spring had been previously abused and the tool wasn't ideally sized allowing the coils to jump and tangle).
I had a bit of a resize with sanding stick and scalpel and tried again and it's certainly got promise, I need to tweak the file to suit specific barrels but it's a simple quick 3 part print using barely any filament.
Obviously not anywhere near as good as the proper bergeon winder but definitely cheaper for the hobbyist, (even if you haven't already got a printer and had to buy one first).
Here's a video of it if anyone is interested, comments and ideas are welcome.
Hi everyone! I bought an Aeromatic 1912 A1308 watch (have not received it yet) and I was wondering what caliber does it use. By chance I found the attached pictures, I believe it's the same caliber but I found no information on it, only that it may be a Seagull. Can somebody help?
Is it possible to purchase parts for a Citizen 8228A (Miyota) movement. I have a rather beat up old example, which is missing the tip of one of the winder gears.
I suspect the answer is going to be, no, you would need to find the parts from another damaged example.
I did look on Cousins, but the part I need is not listed.
Initially I suspected the only issue with it was the balance, and spent a little time tickling the hairspring back into shape, only to then figure out that while the winder made the right noises, it wasn't actually driving the mainspring, due to the missing pinion tip.
Hello there watch fix fans. Here's (I hope) an interesting one for you.
I have this beautiful small ladies 'Fero Feldmann' Swiss-made watch - it came in a bag of "used and to be repaired" watches.
From what I can see, the mechanism seems in very good working order. Just a slight shake and it goes and goes. There is no strap, but that is not the issue here.
The problem is the stem and/or crown. As you can see, there is definitely no crown. But I am wondering about the stem.
The watch does have its case and edoes have, as you can see, a hole where the stem and/or crown will/should fit in.
There is something which appears to be some kind of part-stem at the 3 o'clock position.
Using tweezers I can pull it out and push it back in quite freely. A very small screw on top holds this "stem" in place. I think you can see, in ths second photo, how this "stem" attaches to the rest of the movement.
Clearly I need to attach a crown. BUT what about a stem? A stem extension? Or one of those crowns which has an extended stem-like attachment which should fix onto this current "stem" in this watch?
Yes, the watch face is somewhat scratched, and the minute hand is a little bent at the top. You may say it is not worth my while trying to get this fixed. But I just SO MUCH like this little watch and would LOVE to give it life again! It clearly IS still "alive" - though I'm not sure if it is a mechanical wind-up or an automatic. The latter of these seems to be the case - as I said earlier, a little shake and the mechanism goes and goes. PErhaps with a little oil (and lots of encouragement) it can be made good.
So my main question - what kind of stem/crown to attach and how to do it?

The only markings on the movement are the words Swiss Made, 15 Jewels and a small 5 under the balance arm. I don't currently have a very accurate caliper but I think it is 34.7mm rather than 36.4 as the Unitas 6497 movement wouldn't fit. Here is a picture of the dial side but I haven't seen any writing on it. I do not believe that the movement has ever been changed since it was made in around the 1930s.
I have a nice little carriage clock in for service, very good shape, except for over 0.30mm sideshake of the barrel arbor in the barrel. Thought I would show how I bush these; it seems they often get overlooked or just skipped as they are a little more fussy than just bushing a plate. I measure everything up, then remove the boss in the barrel, and make a bushing that fits from the inside and is stepped, replacing the boss. This way it's captive, and doesn't require a big interference fit to get seated and stay. I turn up the bushing with a boring tool in the lathe, doing the outside as well (running in reverse of course), then do the barrel opening with the same tool. It's a pretty quick process once you have the moves down!
Well the movement is Unitas, but they did make many many different calibers. What is the exact diameter of the movement, and can you get a pic of the dial side? Are there no markings near the balance cock or on the dial side? If not it will take some digging but you will probably find it on Ranfft's site.
I must admit I have never even clapped eyes on one like that, but my gut feeling is that you back off the key in the opposite direction to winding, and it will unscrew, then undo the knurled bolt, and pull on it, and *something* should slide out of something else. The chances that I am completely wrong however are around 50% EDIT: Wow.. Barographs are expensive when new.. https://www.metcheck.co.uk/collections/barographs . I'll need to keep an eye out for one, they look pretty interesting, similar to clockwork seismograph recorders .
Thank you but I should have mentioned before, tried a Unitas 6497 clone movement to see if it was the correct size. The gears are far finer and the escape wheel teeth are the wrong size and it was slightly too short. It has a Swiss Lever escapement as far as I can tell and is about 4.5mm in height. If it helps the mainspring barrel is the size of the winding gear on the top and seems to be fully attached to it.
