Thanks for the link, Adam...
...I think I've seen that report before...?
There's no doubt that suspending a movement inside a case is going to aid the shock resistance of a watch (after all that's what some of the G-shocks do! 
) and as you say it does provide good justification for the size of the case.
My comments are more to do with 1) the direction of the damping - only in a single plane and 2) the complexity of the system given that it's only a single plane of protection vs the 3D protection an appropriate hysteresis rubber might provide and 3) the measurement of 'shock' or impact in 'g's. I couldn't read the graphs well enough in that link. I'll have to have a look at some of my time vg graphs to get my head around it.
Personally, the design is cool. If over complicated....but that's what makes it cool.
JLC's Extreme series: Shock Absorption
If you aren't already aware, JLC incorporates a nonpareil shock-absorption system in some of its Extreme series watches. The Extreme World Chronograph, the Extreme World Alarm and the Extreme Tourbillon include this feature. These watches are actually con...
Very interesting, PeaceFrog
I had not thought about this aspect fo the EWC in a while, and it is good to have a refresher. The shock absorption was one of the many factors that pushed me to get the EWC -- was that true for you as well? The case within the case design is the key reas...
New JLC book on extreme watches
Hi Everyone, I didn't heard about that book. Wo has informations on it. I'm very interrested about it. Best. Marc
Very interesting...
post, this is definitely great to know! Thanks for sharing the photos! Best, Filip
Gentlemen, thank you all for your comments...
Respo: yes, the extra safeguard of this system was a factor in my decision to buy this watch, and this for me, along with the quick-change strap system and 100m WR, solidifies the "wear-it-wherever-and-forget-it" aspect of this particular piece. Even thos...
It was an embarrassing moment
When I saw M. Lambert, I was on my way to someplace where I do not wear nice watches and so I had no watch, let alone a JLC, on my wrist, even though I was traveling with the Polaris on this trip. And I am almost NEVER without a watch! Yes, it was a littl...
LOL, Respo, it had to happen to you! :)
Jerome Lambert is a very friendly gentleman, and I'm sure you had a great moment, speaking with him. If all works well, I will meet him in less than 12 days, now... Will try to wear a real watch, then. Best, Nicolas.
Yes, it was pretty funny.
I was like, "No really, I do own a real watch. I do, I do!" I am sure you won't have any such problems, Vlad, the Prince of JLC. Best, respo
I get no more than 1.5 mm with my EWA
but closer to 1 mm. How are you getting 2.5 mm? Even without any compression I only have about 1.5 mm available.
perhaps my estimate is a bit off
as you can see from the photo with the cushion compressed, my hands were full! I chalk this up to using inches and feet my whole life to measure distance! I'm sure both watches are the same. I really like the EWA, especially the Tides of Time version in S...
For your reference, the crown is about 5 mm in diameter
So perhaps your estimates should be divided by 2 or so?
I was using the thickness of the watch
as a "yardstick" (haha). 14.5mm, I think. I have a set of Vernier calipers, but they're buried somewhere in the garage. So I think you are right, maybe the total range of motion up and down is around 3mm, 1.5mm in either direction.
PF, thank you for a very…
Informative post! Love this kind of posts! Unfortunately I find the Extreme watches to big for my wrist. Would love to add the Tides of Time to my Memo theme… Best Blomman
Interesting, but questions....
...shock is a very quick application of an acceleration. It's not just the magnitude of the 'g's, it's the duration and rate of loading that matter. The shock absorber here is air which will dissipate the shock energy as heat. The problem is that the damp...
my analysis is admittedly unscientific
And I hope my thoughts will come across to you as accurately as possible given my imprecise wording. I, also, would love to see any data that JLC might have, though I assume this is not going to happen. It feels almost like the shock absorber on a car. I ...

wow, very interesting and educational post...
.. enjoy reading a post of this kind... learning new thing every day... full of joy in our life! thanks for your well-written post, PF stefan
