  1. Looking for some insight, does this balance staff look worn out to you? This omega balance has been giving me some issues and this is where I am starting.
  2. Hi All, my watch - raketa (2624 movement) Now the escape wheel can't move itself. If i blow air to balance wheel, the second hand can move . https://drive.google.com/file/d/1ykpAf63N2BUtvVVu1jra0p9hZP4xh9d-/view?usp=drive_link I have reinstall the click from mainspring barrel and the setlever and clutch lever. The other parts is unchanged. is it a problem about release all energy of the mainspring? How can i restore it?
  3. Hello guys i am working on a Rolex cal 1570 balance wheel that stops when is dial down but runs when dial up, i changed the balance staff thinking that was the issue, turns out it wasn’t. the balance wheel bumps and rubs into the pallet fork plate. Bellow I left a picture of the pivots of the balance staff.
  4. Hello everyone. I have a Chinese 6497 movement (Seagull ST36) with a broken hairspring. I can’t seem to find a replacement anywhere online. There are plenty of replacements for 2800 series (Seagull ST21). There also 46940 balance wheels available which look similar. My questions are pretty dumb. Can I use either of these in my ST36? Also, does anyone know if ST36 balance wheels are available anywhere? Sorry to trouble everyone but I’m new here.
  5. Hi all, I broke the pivot of balance wheel on ETA 2804-2. I bought a generic complete balance wheel with bridge for ETA 2824-2 (http://www.ebay.com/itm/262234041099?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and tried to install it without any difficulty. There is only a difference between the new and old one is the shock assemblies (Incabloc vs Novodiac). In the photo below, the new one is the yeallow on the right hand side. My question are: - Is the complete balance wheel and bridge replaceable between those movements? - If Yes, after installed, the balance wheel has swung a little bit then stop. What is the reason? How to fix it? Thank you
  6. Hello A friend of my father gave me this old pocketwatch to see if I could repare it. As you see in the picture, the balance wheel is extremely bent. I tried to bend it back, but i cant make it good enough. Does anyone know where I can find a balancewheel for this Revue 30 movement? I have tried to search around online, however, I cant find any. Is there a generic balance that would fit in here? Best regards Nicholas
  7. Does anyone have any suggestions about how to get this clock to run? It is a Chelsea ship’s clock. When I got it it would not run, but I attributed that to the fact that it was dirty and had old black oil around the pivots. I carefully cleaned the movement and cleaned the balance wheel separately in naphtha. It reassembled without problems and was oiled,but would not run. If I “add power” to the movement it will run. I looked at the mainsprings while it was dissembled and they looked clean and intact. I have included pictures of both sides of the clock and a picture from the side showing the wheel (the one pointed out by the screwdriver) that I can push on to make it run. Thanks in advance for any help with this vexing problem.
  8. I’m working myself through Mark Lovic’s “Watch Repair Lessons & Courses”. Before enrolling I wasn’t sure the courses would be worthwhile to me, as I had spent a huge amount of time researching the Internet on how to service watches, and had serviced several Vostok 24XX movements (very affordable movements, BTW). Now, in hindsight, the courses have proved to be extremely valuable to me. I’ve learned things that I just haven’t been able to find elsewhere, like how to easily transfer watch oil from the bottles to the oil pots, how the get the right amount of oil onto the escape wheel teeth, how to remove rust from pinion leaves, that I shouldn’t oil the pallet fork jewel bearings (and why!). The list could be made very long. Anyway, yesterday I finished the level 2 section of the course, named “Lubrication and Re-Assembly”, and as I beheld the magic of seeing the movement come to life again I shoot a slow-motion video of its beating heart, i.e. the balance wheel. For anyone interested you can see the video here. Thanks for reading!
  9. I'm relatively new to mechanical watches and have quickly become fascinated but have an elementary level question that hopefully someone can answer. If the hairspring and balance wheel come to a complete stop due to the main spring running out of power, what is it about winding that sets the balance wheel back into motion? I understand the way the escapement works once it is in motion to input a small amount of energy into the balance wheel, but don't understand how winding alone sets it back into motion. I know with grandfather clocks you have to restart the pendulum manually and I'm wondering why this isn't the case for watches also. TIA.
  10. I am in the process of servicing the Landeron 48 movement that came with the complete watch with wrong dial applied, as many of you can recall from my other thread. After a brief check I noticed something was wrong with the balace wheel, so after inspection of the part, I discovered that the upper pivot was broken. I had another balance wheel with bent hairspring, so I decided to replace the balance wheel using the original hairpring. After a bit of tinckering, I managed to do just so, but a new problem arised, which will be shown in the linked videos here below. The first video shows how the new balance wheel turns freely after a bit of adjustment in the movement: The second video shows the problem I faced after replacing the hairspring onto the balance wheel and reassembling everything back together. Basically, the amplitude is extremely low, but I cannot figure out still what can be the problem. The second video above shows the issue better than a thousand words... I need the help of the experts, here: what can the issue be? I followed all Mark's videos on putting the watch in beat, checking the pivots, pallet stones, everything. I have never seen such behaviour before. What can it be?
  11. Hello All I have started my watch repair learning! I have read a few online guides on how to repair watches. I have also acquired most of the necessary tools for watch repair. I have started out by cleaning two watches. The first watch I attempted to clean was a Bulova 10AK movement watch. This watch did not run before I cleaned it, nor after! Before I even took apart the watch, the balance wheel was wiggly. I could easily rock it from side to side. This is what I think was causing the problem. I cleaned it and put it back together but it still didn't work. Could someone explain why the balance wiggles like it does and how to fix it? This also happened on the second watch I got: a Hamilton 982 movement watch. This watch ran before I took it apart, but after cleaning it, its balance wheel has the same problem! I really do not know what to right now, so any help would be appreciated! A few more questions: - How do professionals make their movements so clean that they sparkle after cleaning them? I used an ultrasonic cleaner for my second watch, but the results were good, but now perfect. - Both watch cases aren't in very good shape. Where could I send watch cases to be restored? - Where should I send a dial to be cleaned? - Should I have professionals repaint the hands or should I do it myself? - What kind of crystals would you recommend for each watch? - What gasket should I get that goes in between the case and crystal on the Bulova? Any help with any of the above questions will be very helpful to my learning experience. Thanks!
