I was simply pointing out that they aren't "rare". They are, however, excellent watches in every respect. GP had great success with their HF Chronometers in the Observatory trials, and the fact that so many have survived in good condition is an indication of their quality. I have owned quite a few, and yours certainly appears to be a very nice, original example.
As indicated in the ad below, these watches finished 1st through 5th in the 1970 competition!
