Actually it's a PanoGraph - the PanoRetroGraph was a more limited watch and much more expensive that the PanoGraph. As you can see in the movement shot above, it has a Cal. 61 marked under the rim of the balance. The PanoRetroGraph used the Cal. 60. Cheers, Al
Lovely watch - it was the first German watch that I seriously considered, and the movement is delicious. Too bad for me that it was too big and thick for my slim wrist, but it was undoubtedly a pretty cool watch!
