Replacement parts EB 8400

Recommended Posts

Hi, 

I have a problem I'm hoping you can help me with.

I have an EB 8400-74 movement and have managed to loose the balance jewel. It's an Novodiac shock protection but I have problem finding the correct dimensions to order.

Does anyone have any idea where to find thsi information?

Welcome Johan,

If this is the same Novodiac system as the Bettlach 8800, then I have spare balance jewel and setting. I am not sure if its the same, but cousins does note this as the same part for the 8400-74. I can't find any images for the movement, so can you post a pic?

Got it Johan. I'll be home in a couple of hours and will check through my parts. I know for sure I have EB 8800, and I can send you that for you to try, but I also have some other Bettlach movements I can check. More to come.

Awesome! But I must warn you, I live in Sweden so I don't know how much the postage will be...

I wonder if an inca-jewel might fit? 

I might have a few of those myself. I guess it won't hurt to try...

@Johan I found three Bettlach movements:

an 8461 complete movement and I can send you the balance jewel setting and spring or any component thereof,

an 8800 complete setting, jewel and springDSCN5055.thumb.jpg.62b09825794cd5ca27b8630d1554a7dc.jpg

 

and another type of 8800 balance setting with KIF spring but I can't find the jewel (lots of smal envelopes to look through).

Will any of these work?
