balance stops swinging at certain angles

Recommended Posts

hi everyone,

today I was working on a watch (the movement was eb8810) and after I was happy with the result I put the movement under a. glass, come back to it 2-3 hours later, still ticking so I put it back in the watch case and after about 15 seconds it stoped ticking as I started to move it around I don't know where to go from here wether or not it needs re-oiling or a new part in the balance operation, this is not the first watch I have experienced this in and didn't end up doing anything with the other watch.

thanks in advance, 

Ali

p.s I am looking for an eb8800 movement in working condition so message me if you have one

      I have removed the rear cover and taken of the winder and unscrewed the screw hold the movement
      the movement is free within the body, however I cannot see how to remove it from the body. Any suggestion or help would be most welcome. Regards Rob1949

      Hello Everyone.
      I need some help with repairing my Emporio Armani ar-1922.
      I've watched some videos on YouTube but none of them resemble the movement of this particular watch.
      My first problem is removing the stem/crown. I cannot see anything which looks like it will release the stem and I don't want to poke around inside it any more for fear of creating any damage.
      Any help will be much appreciated.
      Thanks.

      All,
       
      Some of you will know that I have been working recently on a vintage movement. It's an Omega Ca. 266. from 1954 according to the seller - presumably based on the serial # from the movement.
       
      I decided to give the movement a full service - as I didn't know the service history. Which after stripping down the watch, it was apparent that it had been serviced in recent history. As everything was incredibly clean and all lubricants still clean and fluid. Of course, I wouldn't have know that without  stripping it down.
       
      After reassembly (following cleaning and fresh lube) - most everything seems to be in good order. But I can hear a funny (odd) "ting" noise in the heartbeat when the movement is positioned such that the balance staff isn't vertical (isn't dial up or dial down).
       
      I assume that the noise is coming from something in the balance. But I don't see anything too weird on the timegrapher. Other than too much beat error (1.2 - 1.8 ms depending on position).
       
      So, two questions (I am assuming this isn't normal or healthy)
       
      1) What would you check for?
       
      2) How does one correct (or improve) the beat error on a balance without a beat correction? I am guessing that the hair-spring would need to be loosened at the stud. Then position the balance to the center position and tighten the hair-spring stud? Or something like that.
       
      I am seeing about 250 degrees amplitude dial up or down. -4 sec/day. Down to about 210 degrees with the balance staff horizontal. Not much variation in the timing. Worst position was -9 secs. Most about -4. Best +1.
       
      If I hadn't put the movement up to my ear, I wouldn't have any idea that something was "off".

      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

      20190925_101850_1.mp4 My Oris dropped onto the street, no cosmetic issues, rotor spins hands move everything seems in order nothing's rattling inside, yet it's completely dead!?? That 7750 kept better time than my Muhle and Tudor, real workhorse, maybe something really obvious I'm overlooking?
