Hi all -- I'm still climbing up that steep learning curve for this reference, so please indulge another question. It appears that most 3940s have solid case backs. Did Patek even make platinum exhibition case backs for the 3940? It would be a shame not to...
To my knowledge the platinum 3940 was only ever produced with a solid case back. I suppose it’s always possible that one could have been made by special order, but I’ve never seen one.
