You should have posted the link: PRIM

Otherwise many of those interested in PRIM watches of Czech origin might be redirected to the low-quality Chinese Prim producers or rather cheaters.

G'Day !

 

Well, I have a question, it is regarding the PRIM cal 684 (? 68.4 not quite sure, as the marking on the movement is not quite clear).

 

Namely, I need information about the balance staff, either the replacement equivalent from Ronda or the actual sizes so that I can find an equivalent or if none then to turn a new one. The staff is shockproof KIF S.

 

Thanks in advance!

 

Cheers

G'Day!

 

I have once again closely examined balance of the 684 movement, and have noticed that the balance staff is friction fit. Thus I removed the balance spring, roller and the balance staff with a broken upper pivot. Next thing was to measure the staff as accurately as possible. To measure it I used the JKA bench dial micrometer and my Srb a Štys measuring microscope. The results of the measurement are given below in a drawing of the balance staff in hundredths of a millimetre. 

 

Unless I can find a similar staff which can be modified to suit I shall have to turn a new one from scratch.

 

Cheers
