Desperately wanted to buy the Clous De Paris version in my early days of watch collecting but alas, my pockets were not deep enough then and I never came across one in real life.
My other pick would be the Gordon Circulaire which I have seen. The retailer also had a Rayon Flamme but it did not appeal to me.
Have rarely come across these pieces for sale locally and the 2 that I have seen and handled had been carelessly polished resulting in the case lines being rounded.
Good spot as always Emmanuel. Would you know if there are many shaped movements that are chronometer rated?
