Dear Nico, why don't you like the lugs of 5575G? They are very "fluid" and with interesting contour. I agree it is one of the most charming and romantic Patek WT!
its the reason I love it- its flaws, these are watches with a soul, too much perfection kills a watch. But to be honest on the wrist- it works perfectly
Recently I was offered a "double sealed" 5575G for a reasonable price. Later I found out it was a used watch which was sealed by Patek when it was sent for service and I didn't go ahead with the purchase. A friend of mine has a double sealed 5575G too, he does not want to sell it at the moment but I am hoping he would change his mind soon.
