Hi, my name is Ross. I am a rookie watch enthusiast and I am really puzzled here.
Could someone explain to me what kind of a problem am I facing with my timegrapher?
I do two sets of measurements with the same watch (1 day or 6 days apart) and receive vastly different results - to the point of being completely different from what I observe in real life.
For example, my timegrapher shows that my watch is running fast (or ahead of time), while in real life I observe that it runs 7 seconds per day behind. I even recorded a video about it so you could see it for yourself: https://youtu.be/mhGzf6aLMlY
How should I interpret that? Am I doing anything wrong?
I work a lot on small caliber (ladies watch size) movements but still have mishaps with the balance hairspring. These hairsprings are very fragile and easily bent and removing/replacing the balance assembly seems to be my problem. I would like any comments on the risks of deforming the hairspring by allowing the wheel to dangle during handling. I would also like to know if the position of the regulator arm/pins has any effect re risk of deforming the spring, should it be close to the stud or as far a possible from the stud, I normally leave it where I find it so the timing is close to what it was before dis-assembly. Any advice on techniques etc will be much appreciated.
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
I am correcting a deformed hairspring and need to set the curve for the regulator pins. De Carle mentions using curve-forming tweezers, which I cannot yet find. What are the alternate practices for forming this curved portion of the over curve?
Hi again all,
since there are some really knowledgeable people here I hope you can impart some wisdom regarding repairing a bent hair spring. after getting this old movement working again with the help of this group (new mainspring), I need a little more advice.
after hooking this beaut up to watch-a-scope it shows low amplitude and very erratic trace. I can see the hairspring is bent and need to start here in addressing the issue.
What tools are needed (not willing to spend £50 on hairspring levers at the moment)? I have basic tools (enough to service a movement), but what are the essentials for working on a hairspring? i.e for removing from a balance safely what tweezers types/sizes are recommended for correction etc.
Also, is there an easy way to identify and obtain replacement hairsprings? I assume they are very interchangeable as it would not have been easy to make new hairsprings for every watch model.
I have been scouring the internet for a escape wheel or any parts sheets for a gruen 730ss with no luck.
Anyone know of anywhere i may get a bit more info or parts for a gruen 730ss?
Don't seem to be a lot out there, on them.
Any help much appreciated.
