Hereby I´d like to announce, that I am ready to find out a answer all your questions, if it is in my powers 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.

Dushan Grujich Posted August 13, 2016 Report Share Posted August 13, 2016 (edited) Well I would like to welcome everybody from english speaking world who is interested in Prim watches. Hereby I´d like to announce, that I am ready to find out a answer all your questions, if it is in my powers 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 Dushan Edited August 13, 2016 by Dushan Grujich Link to comment Share on other sites More sharing options...
Dushan Grujich Posted August 13, 2016 Report Share Posted August 13, 2016 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 Dushan Link to comment Share on other sites More sharing options...
Dushan Grujich Posted August 14, 2016 Report Share Posted August 14, 2016 G'Day! To conclude. Unfortunately, there were no luck in finding similar balance staff, thus I had to resort to turning a new one from scratch. The watch with the prim 684 movement is now working as it did when it was new. Cheers Dushan Link to comment Share on other sites More sharing options...
