Girard Perregaux

I have see this ad, but my French is a bit rusty...

 

Not sure if the text actually refer to a specific collection like the JLC 125 Jubilé.


The ad is from 1960, but the 170 anniversary would be in 1961...

I haven't found any document showing a special collection of 7 pieces. 
But I still don't have that much GP documents...

If I had to guess, I would say that:

7317 - Auto/Date
7372 - Auto/No date
7373 - Auto/No date
7199 - Auto/Date

+ 3 more? 
All 39 Jewels Gyromatics.

Why 7? Because the Gyrotron has 7 ball bearings?


Even close?
