Girard Perregaux - Help! Can you ID this GP???

Help! Can you ID this GP???

Hello,

I found an old watch my father owns and would like to know from what year it is. I have searched online for information and I can only guess it's from the 50's or 60's. My intent is not to sell it, we are just curious to know more about it. My father purchased the watch at an antique shop en Buenos Aires, ARG for USD$150.

Under the GP it says 17 Jewels and below it says ANTIMAGNETIC.

Any help is appreciated.

Thanks,

Jovan

... a manual wind, 13 Ligne (about 29mm) movement beating at a leisurely 18000vph and with a power reserve of 41 hours. It was made until the mid 1940's but still being cased up into watches in the late 40's. It is difficult to give you information on the...
