enamel painting. Look careful and you can see the word "email" (French for enamel) close to the tail feathers. Most likely done by Anita Porchet and hence it is a very rare piece ! If you like it, go ask your AD to get your name on it. Good luck !
I appreciate the information. Anita Porchet certainly does some amazing enamel work, not just for Patek Philippe, but for other Swiss watch brands as well.
Although the eagle in enamel looks quite nice, they are probably already sold to collectors who had a private viewing at Basel. My hope is to receive an enamel dial world time before they are discontinued
