Hairspring CGS & specifications.

Recommended Posts

How do I find out the CGS parameters and specifications needed to place order with the hairspring producer.

What tool to measure torque vs radial displacement with?  I have heard of ergometer.

I am sure the subject has been previously covered, no luck with the search function.

Thanks in advance.

Best to contact the hairspring producer.  Years ago you could get charts for this sort of thing. These days I think it is beyond most watch repairers.  

How can you contact an hairspring producer. There are only like 2 or 3 in Switzerland and they don't correspond with repairers or individuals.

You stated my next question and answered it. My order would be for five hundered HS which I don,t think meet their MOQ either. So back to fixing HS?

Not all hairsprings are produced in Switzerland China and India must have domestic production of hairsprings, and this British firm manufacture custom made Hairsprings and carry's a large range in stock.

Correct, and as you noted the British has a website and contact info. The Swiss have the website and a marketing but only talk to mov't producers when obliged by regulations and wide trade agreements (see link below), and good luck about talking to Chinese for less than 1,000 pieces. I'm not aware of any production in India., the only remaining producing country is maybe Russia, then we have Japan and the countries where they own factories, but both of them don't produce to customer specifications.

I don't think you will have any luck talking to manufacturers, and only with the old way of scouring Ebay can ger you a solution.
If you have trouble with shipping or paying from your country just PM and we'll find a way.

Hey we could make a WRT mov't , limited edition 1,000 pcs, ahaha
Yes if you post interest on Chinese websites you will get follow-on emails. That is just proper marketing, as invented in America 200 yrs ago. My own country telesales are worst.

I used to keep radar on ebay, only usual assortments. Lets find the merchandise first, I can arrange for payment through my niece attending school in oxford. Have problem with making small payments only.

Thanks for your help offer, very kind of you.

It would be absolutely doable, check for example "chinese watch group project" on WUS. But as it happens this is more a repair site than a collector's one, so I doubt it would raise enough volume. Then again, stay tuned for crowdfunding projects by the usual suspects.

Ya, collectors ideas. I enjoy repair, just drifted into collecting.

    • I got this little beauty  at a swap meet on Sunday.  I changed the battery and still nothing.  I know nothing about quartz. Is there a trick I kneed to know?  Is it worth taking down to be repaired?  Should I look for an ETA movement to put inside?  It does have the gold matching band in good condition.
    • So jdm if you want I can mail you the watch of your dreams.

    • Thank you AndyHull and JerseyMo for responding with really helpful instructions!  You guys rock!  i have to get some rodic to help hold these two little mini-monsters in place. I was trying to use a small bit of sticky-tack but it didn't hold well enough.  I would get the screw into position but it would fall over when the screwdriver touched the screw.   For the 24 movement that still has the broken screw end in it, I will try to get that out after I get the lever and screw installed in my working 24.  And yes, I will install the crown/stem AFTER I have the lever and screw in place on the plate. Again, thanks for your help- i really appreciate it!!!  Will let you know when I get things back together.
