Jean Lassale 1.2 mm mecanical movement. Any info and scan ?

A friend recently told me about the Jean Lassale watches, and their ultra-super-mega-whoaoh-thin movement.

They made a handwound mecanical movement of 1.2 mm, and managed to put it in a 2 mm watch. With crystal back !

They also made an auto mvt which was in the 2 mm heigth.

My friend also told me that they are super rare, and also quite fragile, as putting too much tension on the strap resulting of the watch to stop, because of inner strengths.

Up to now, I thought that the JlC Utra-thin watch was cool, but the Jean Lassale is way above it.

I've searched in vain on the Net for info about this movement. I found some Jean Lassale watches, but they are REALLY ugly. I've heard and read that the Jean Lassale company was founded in 1975-1980, spent some millions on designing and producing the 2 movements, and a few years latter, went bankrupt. Seems like Seiko bought the name, and now, Seiko-Lassale produces some crap watches.

I know it doesn't have much to do with the ACHI (or AIHC, AHCI, ICHA, IHCA, HCAI, CHAI, CHIA, or whatever the order), but I believe that this very little known company that lived for a couple of years and produced what looks to be like one of the most impressive watch movement (with, of course, the Poljot Mekanikal) should have it's place in the "Haute Horlogerie" section.

So, any extra information and scans would be greatly appreciated.

Thank you very much.

Nouvelle Lemania owns the rights to these movements now...

The 1.2mm hand-wind is now Lemania calibre 1210, and the 2mm automatic calibre 2010 is the same movement with an auto winding module. The trick to the design of these movements is that there is no top plate in the conventional sense. Everything floats on ...  

A little more...

Hi, The Jean Lassalle cal. 1200 (manual wind) and cal. 2000 (automatic wind) were introduced in 1978. To achieve their extraordinary thinness, they dispensed with bridges and used ball bearings instead of using jewels. Jean Lassalle cal. 1200: 20.8 x 1.20... 

Thanks Stephen...

Hi Guys, I'm definitely impressed from a sheer "wow" standpoint but they seem like maybe more of a novelty than useful movements. What kind of service interval would these suckers need (ball bearings?)? I'd love to have a close look at one, thanks for sha... 

Might be able to answer you soon !

Yes, my questions were not that innocent. I am in the process of getting one (handwound). From what I've heard, it's a VERY VERY delicate watch, so thin that if you put too much presure on the strap when you close it, the watch stops. I don't think I will...
