Interesting.
I like innovative challenges by the watch brands. Interesting features, indeed. Practicality for a long run and retail availability aside, as a concept watch, this is a very attractive one. Vacuum seal durability or how to service or how long this fiberglass spring will last are some questions to be answered, but it it is used for a future watch, I would be very interested. Obviously, much more wearable than Lange 31 
Thanks for the scoop, SJX!

Announcing the Cartier ID Two concept watch with 32 day power reserve!
Just yesterday Cartier presented the ID Two concept watch to selected members of the global watchmaking press, at its manufacture in La Chaux-de-Fonds. I am still travelling so here is a quick overview to explain this remarkable new concept watch. An in-d...
vacuum is a bit over the top, true.
Yes, it might do contribute also its share to accuracy and power reserve, but is it really worth it? If they want to bring a service free watch into the market then this feature is redundant. Thank you for the info. Moritz
i wonder how people would feel about the fiberglass part...
not exactly a 'romantic" or "elegant" material. the watch looks nice but i also wonder about the ceramyst implementation (it's way up there with windshield or at least it seems that way). great tech for sure to have that kind of a reserve. personally, i'd...
Regarding the vacuum..
How is the vaccum be maintained when setting the hands and winding the watch? I do love the concept through and the use of fibreglass and clear ceramic actually enhances the geek technical appeal to me. The high reduction gearing is also a nice touch.
There's no leakage through the crown
Cartier tested it and found no leakage; apparently the gap is too small to be significant. - SJX

Some answers
The vacuum seal lasts 10 years before time keeping starts to deteriorate. And the fibreglass mainsprings are coated with Parylene, which improves their durability into decades. - SJX
tempting!
sounds promising. Hope to see the actual products which utilizes these innovations one day. Ken
I'm astounded by the innovation....
I recall that Andreas Strehler had re-conceived the tradition gear train with his "Papillon," but the ID Two gives us a traditional hour and minute hand, which I prefer, as I suspect most watch enthusiasts do as well. I'll look forward to reading more abo...
So winding the watch....
Is not an issue requiring a key like the Lange 31, because the fibreglass mainsprings store more energy and deliver more stable torque without having to increase to huge lengths? Or does this watch take an age to wind?
It's similar to winding a regular 8 days watch
according to Carole Forestier. I can't remember the exact number she told me but I think it's 120 turns of the crown, while a normal watch is 40-50 turns. - SJX
Nothing specific
Cartier just wanted to prove what is possible. But personally I feel this is to prove that a practically sized watch can run for longer than a month, which is the next milestone after the 7 or 8 days (one week) watch. - SJX
