I would think that this is more a retaining clip vs a shock spring. I recall another forum member mentioning this about the Kif duofix. He described that for a third or fourth wheel where the pivot didn't have a substantial shoulder to contact the hole jewel to arrest the shock beyond the 'spring' giving way, this shows that the spring/clip really was meant as a retaining device for the cap jewel. The incabloc style shock system allowed for the spring to absorb the smaller shocks and, if significant, the shoulder of the staff would contact the hole jewel to further protect the pivots.
This set seems even more versatile, but perhaps I'd be taking a bigger risk, and having to wait longer? As long as we're not talking about several hundreds of pounds I don't mind paying a bit extra (cousins) and get something that actually works.
Hi all time fans!
short intro: I am Gertaap from NL and I am like Russian time technology a lot. I have many Poljot, Vostok and Strava’s and I have been collecting them for some years. I do also service the watches to practice.
My my favorites are the 3133/31659 Shturmanski and the 2809 Vostok chronometer movements.
I just bought a very nice MIG clock too, a bit bigger than my other collection...
I also have some Swiss watches but i like the no nonsense working horse movements from Russia!
