anti-shock

[gary17]

HI

Is it possible to replace the anti shock unit on a balance cock. I have removed it from the balance.The 2 clips either side that hold the unit in place had snapped.

Its just the unit i need i can replace the jewel.

Or do i have to replace the whole balance cock unit.

Does it need to be the same make.

like a tudor watch would need a tudor balance cock unit.

thanks

It depends upon who made the watch. As the others have indicated we need more information like the make and model of the watch.

Hi

It's a omega cal 620.

Thanks

I have done this fiddly repair recently on a 620, so it is possible.  First you'll remove the hairspring/balance from the balance cock.  Flip over the balance cock and you'll see the u-shaped clip that is holding in the incabloc setting.  I would recommend installing the new shock-spring and cap jewel into the setting before installing back into the balance cock.    

You can scavenge a new shock-spring for a reasonable price from www.ofrei.com , part:FB-INCA-ROA466

Shock protection unit is specific to the caliber. It,s failure results either in broken pivots or the spring jumping out.

Just in case you want all the numbers I have them below. But it looks like The assortment FB-INCA-ROA466 Is a better way to go because you get spare parts.

Just replace the broken shock springs.

The spring is most likely manufactured by Incabloc, so can do what Clockboy suggests. I keep scrap movements for this sort of purpose.

Thanks everyone. I have ordered the part.
