Seiko uses Diashock system...
"The 7S26 uses Seiko's patented Diashock shock protection [3] on the balance
pivots, has a soft, plastic spacer ring [4] closely integrated with the movement
and a relatively low mass rotor [5] that is unlikely to bend or break even with
very severe shocks" http://www.thepurists.com/watch/features/8ohms/7s26/ BTW, thanks! HAGWE! ^_^
Do we really need Incabloc or KIF these days?
Or can they be safely left out of a movement's design? Your shockingly inquisitive, amerix
hmm...
Helo amerix, Provocative question: Were they ever necessary? Most definitely yes. Broken balance staff pivots were exceedingly common before shock protection became the norm. Has something changed? Not really; we're sportier and more active than ever and ...
Yes...
Anti-shock is no longer a subject of discussion these days, but only because the Incablock and KIF solutions work. If we left them out we would again be having problems. Just imagine the size of those balance wheel pivots... 0.08mm in general. Very hard t...
Thanks John and Don for your responses
When starting a thread I always end up at the bottom of the frying pan and not safely (!) above where the vapor and aroma can develop into an enjoyable discussion. Nothing at all against shock-absorving techniques! A-L Breguet tried this with his "parachu...

A wonderful article
that deserves careful study (give me another hour or two!) not only for Diashock. The judicious use of plastics makes a lot of sense in this context. Thanks very much! amerix
KIF, Diashock, Incablock, etc
are all very important in preventing broken balance staffs yes. Especially with the increasing wrist activity and shock that the watches are exposed to.
