Hi,
The watch I got in July was a Girard-Perregaux 1966. It is not a chronemeter (although quite precise) as it is not certified but it is a Tribute to the Centenary Prize of the Neuchatel Observatory given to Girard-Perregaux in 1966.
I love those simple watches dedicated to precision.
Thank you for your interest.
Cheers
Dje
