An ideal situation would look like this: Not long after the sale of the watch in 1969, it went back into https://zzb.bz/glhDc8 link Patek for servicing. https://zzb.bz/pScje8 link During service Patek swapped in a 3417 dial. It wasn't entirely unusual for watchmakers, even in the hallowed workshops of Patek Philippe, to swap in dials from another model if it served a purpose. It does make sense, given the anti-magnetic properties of the movement inside the watch, for Patek service watchmakers https://zzb.bz/2qDpgZ link to use this dial. https://v.gd/xGMngX https://tinyurl.com/22hsjkd2 https://tinyurl.com/4c3ypsb6 https://toolbarqueries.google.nl/url?q=https://www.orologireplicarolex.co/collezione/rolex-sea-dweller/ https://images.google.hn/url?q=https://www.orologiomgit.com/orologi/constellation/ https://www.metooo.es/u/68a046e3d96ba3347ec19066
