Dear kirkdj,
The watch shown CANNOT BE AUTHENTICATED by Piaget.
The history department recognised your images from a set of 8 photos they also received in 2011.
We tracked down the retired Piaget sales director who worked for 40 years on secret watches and none of the components shown are consistent with his recollection of Piaget secret watches. I will not go into the specific details (case, dial, metal weave, gem-setting, cover, logo) are all NOT Piaget.
Piaget never sold 14K gold watches in their high jewelry secret watch collections.
It would be of course very interesting to have a picture of the movement to see if it is engraved as "PIAGET"...
I am sorry to bring this information.
Regards,
MTF
