We did Incabloc, now how about KIF?

Oct 13, 2010,19:22 PM
 

Incabloc may or may not have been the first balance staff shock absorber system, but they were undoubtedly the most successful early entry.  So strong was their market position, that they impelled many watch manufacturers to print the word "Incabloc" on the dial (see Dr. No's watch in the previous thread)!  Naturally, watch manufacturers were less than happy about this, but doing without shock absorbers, once they were introduced, was not viable.  Also, witness the Incabloc ads in the previous thread, where the marketing was direct-to-consumer, in an attempt to build awareness and have the consumer demand this feature in his new watch.

This type of market strength/abuse leads to rapid competition, and KIF Parachoc S.A. of Switzerland was one of the companies to enter the fray.  Supposedly, the name "KIF" comes from the Arabic "kif kif", which means "same same".  This signals that the company was marketing to watch manufacturers ("we are the same as that hated supplier of yours") rather than consumers.  Thus, it seems harder to find ads for KIF shock absorbers in mainstream publications. 

I have not read or heard that there is much practical difference among the various shock protection schemes.  Perhaps a watchmaker can comment on their effectiveness in the real world, and also on their relative serviceability.

In the past, KIF was a major supplier of manufacturers such as Eterna and JLC.  Rolex was an early adopter of KIF, reportedly because of the "Incabloc" dial text issue, and they continue to use KIF shock absorbers in their watches today.

Going to the KIF Parechoc website today, you will find they are specialists and experts not only in shock protection, but "décolletage" as well.  Ooh la-la!













For further reading, try "Shock Jocks" in the Oct 2007 WatchTime, which is a good short history of shock protection.  The last photo is credited to J. Peter of watchmakingblog.

Well written, informative and amusing to boot. Thanks, tee. When you look at that KIF model in the last photo, it really brings home all the elements you'd need to balance to create an effective system, jewel curvature, clearances, spring forces, lubricat...

Thanks, and your real-world experience with a troublesome KIF is interesting. I have a vague memory reading once that the lyre-shaped Incabloc clip could be opened like a door hinge during disassembly, whereas the KIF system required extracting the clip u... 

Another very interesting post, Tee 530.

I have also wondered what, if any, practical differences there are between the common shock protection systems available today.. I have some old watch part catalogues from the 50s and 60s, and there used to be dozens and dozens of different shock protecti... 

Dozens...

I'd hate to think how many there are...If you look at tee's adverts you'll see that the KIF 370 and the KIF A are slightly different. The 370 is a three prong while the A is a four prong like a clover. I have no idea what functional difference they might ... 

Interesting, thanks for sharing. [nt]
