Hairsprings

[carpioboy]

Hi Guys,

                 May i ask where you get your new hairsprings from . I understand that i can buy a donar watch etc but that becomes a little expensive with good quality watches.

  Are there any companies out there that sell new hair springs ?

 

 Thanks for your help

Depending where you are hailing from, but I buy all those parts from either ofrei or borel! Hope it helps.

 

Cheers,

 

Bob

You can purchase from the company below. However most of the hairsprings supplied are without collets so fitting the hairspring to a collet is a challenge. I have used them but they are very slow to deliver.

Nice one clockboy !

 

I have a watch repair that's been stopped for ages due to a broken hair spring !  I'll give them a go.  :)

Interesting site. 

 

How do you measure a hairspring to determine its replacement? I don't have the equipment to measure a torque in g/cm/100^o 

 

...and i don't think the torque wrench I use for my landrover will be sensitive enough  :thumbsu:

 

Or is it a case of measuring the outside diameter and deciding it looks "quite thin" or "thick"
