jean lassale movements used by piaget

NO YOU ARE WRONG!!! well half wrong. if you didn't notice the movement on the left is the back side of the 20P. the movement on the right is the backside of the 25P. the 25p is just a 20p with a .8mm rotor on the back, easiest way to prove my point is you can see on the right movement on the center bottom hidden under the rotor you can see the exact same 24kt barrel the 20p on the left has at 6 o'clock. you need to put up a picture of the front of these two movements, these are the only movements in history where literally every moving part is a "hanging" part.

20p hand wound 1.2mm (Jean Lassale 1200) also used as Vacheron Constantine 1160
25p automatic 2.0mm (Jean Lassale 2000)

25p split to 20p+rotor

front of 20p and 25p as you can tell because it has an hour wheel in the center

By: Bruno.M1 : March 17th, 2013-06:37

I know nothing about Piaget, and definitely not those 40 or 50 year old pieces Is this genuine ? movement looks poor but I dodn't know how a 50 year old Piaget should look like And what is it worth ? I know we don't like to discuss prices here but I have ...

I would say real

Some parallel JLC history

By: MTF : March 19th, 2013-21:02

FrX, The Piaget boffins are searching their archives so we don't know the answer yet. In my research, I found some history of JLC (Jaeger leCoultre) that surprised me. JLC, a so-called "true manufacture", used A.Schild movements for a short time in 1970s....

Well, Melvyn, AS movements were also housed on some Jaeger Watches...

By: amanico : March 20th, 2013-00:31

Such as the Diving watches from the same era, and used outsourced movements for their chronographs, too. But the vast majority of their watches ( My guess estimate is that we are around 90 % ) used in house movements. There are not a lot brands which can ...

JLC has more than 1000 in-house movements

By: MTF : March 20th, 2013-09:52

I completely agree than JLC has nothing to prove as what we call a "true manufacture". Maybe we should tighten up this so-called definition of manufacture? We should have true manufactures and ultra-true manufactures :-) Regards, MTF

That would be an interesting criteria. ;) [nt]

Jaeger LeCoultre is THE definitive watch making mouvement..

By: Sandgroper : March 23rd, 2013-03:53

house, no doubt about that. However interestingly the very first Reversos had an out-sourced mouvement made by Tavannes Watch Co. Tavannes was a company started by Henri-Frederic Sandoz at Tavannes, a very small village in the Jura mountains. I personally...

I can't wait to get the answer from Piaget! [nt]

Working on it

By: MTF : March 21st, 2013-03:28

So far, new generation of personnel have no knowledge of Piaget ever using that movement. They are asking the old-timers back in the hills to confirm the ancient history. You must be patient, young padawan....... Regards, MTF

Wait until next week

Bruno, Its the weekend so we won't know for sure. Wait until next week when people are at work. Regards, MTF

gold plated

By: Bruno.M1 : March 20th, 2013-02:01

I'm almost sure the case is not gold but gold plated, this and a lousy movement ... :-( I thought they were always high end. I googled quite a bit and saw similar movements so I guess it is real but I'm surprised by the lack of quality

I think I have a hypothesis

By: MTF : March 21st, 2013-23:30

et al, I have a hypothesis but am waiting for Piaget to confirm certain things. Although Piaget has been making movements for other brands since 1874, they only started using their name on the dial as a Piaget branded complete watch At the start of Piage...
