Hello all. I am currently working on an Oris with an ETA 727 movement requiring a new balance staff. Ideally I would like to swap it out with a NOS balance complete. I have found a balance complete but for an ETA717, not the ETA727. Does anyone please know what the difference of between these two movements? The Ranfft website shows both movements and details them both the same. Furthermore, would it be worth me taking a chance buying the ETA717 balance complete for my ETA 727? Kind regards.

Thanks all for your reply. Apologies it’s taken a while to get back to you but I’ve been away from home and unable to use my pc. Anyway, I did order a nos balance complete for a 717 and I’ll keep you all up to speed on how the repair goes. Kind regards Deggsie

      Is this a 'hack' ?

      By dnhb · Posted

      The plate is OK, thanks. It seems the answer to my question is that this is a 'hack' & for me another reminder that in general, one won't be the first person to be tinkering with an old timepiece!. As you day, I've been fortunate to have gotten some good advice and, just as important, encouragement. I've been lucky then not to have the balance spring break as a result of my novice 'ministrations' - but I did remember to 'stroke' rather than bend per se. The clock is of sentimental value to the owner so I'm relieved to have now got it running to time with the support & encourage of forum members like yourself.

      In think you are effectively shortening the coil by shorting out damaged tracks. In my case as long as the continuity was good and the resistance not too greatly affected it should be ok .  One was on an era  movement,
