    JLC Shock Protection on Cal. 830/CW

    Hi Forum,

    Another newbie question from me regarding the identification of vintage watches. If you take a look at the following two pictures you'll see that the shock protection systems seem to be different and yet the calibres are both indicated as 830/CW:

    Why would this be the case?

    Quality, improvement, cost?

    About this time shock absorbing systems were being invented and improved at a rapid rate
    and later runs of calibers from various manufacturers, besides LeCoultre, can be found with
    different shock systems.

    Actually, one indicates its caliber as a P830/CW (as seen beside the balance cock), while the other looks to be a K830/CW. All the "K830/CW" I've seen have the same shock unit. I believe the shock system is a Kif, which may be where the "K" comes from. For that matter, I think the other one is a "Parechoc". Draw what conclusions you will.

    I also think that it is just a movement generation thing. Let's face it - some movements that were around for a long time started with no shock proofing and then moved on to various forms thereof. The "clover leaf" type in your example is the "Kif Flector" system, the other looks like the "Parechoc" system.

    There are no conclusions to draw. You hit it right on the head!
