Chopard PW with IWC-movement??

15 years ago I bought a wonderful Chopard pocket watch, probably fitted with an IWC-movement. I am sure that it is a c.95 or c.952.
But on the movement there are no IWC marks or numbers.
I tried to get informations from Chopard, but they did not answer.
To compare it better, I have added a picture with an IWC c.952 numbered 2025668.
What is your opinion, has anybody heard that IWC produced movements for Chopard?

I've enquired about this curiosity with someone at Chopard, and this is what they have disclosed:

“Anne Walter sent this info. We have a similar piece in the museum, luckily!

Pocket watch
Lepine case, 18 carat gold with L.U.C. insignia
White dial with Chopard Geneve, 11 roman characters
Small seconds hand at 6
Breguet hands
Mechanical IWC movement 952, 38.35mm diameter, 19 jewels, 18000 Hz, regulated in 5 positions, 16 ¾ lines (?)
Breguet spring
Year of production: 1976
Reference: 3024
Diameter: 49mm
Height: 9mm

During this period, Chopard did not produce its own movements, and purchased them from outside sources. There were many different calibres; at the museum, we have 30 different movements.”

I know the old posting, the Chopard snd the Tiffany watch are in my collection.
The difference to the other is the lack of any IWC signs on the movement of the Chopard watch.
I tried to get any information fro Chopard, but they did not answer.
So I am very glad to get these informations from Nelson!!
