Just wanted to inquire, how can one tell if the watch they're looking at has the 315 base movement or the 324 base movement? They look similar.
I would prefer the 324 movement because of the 28.8K vph over the 315 movement; the slight sacrifice in reserve power is acceptable to me.
By the way, the Patek website still says that the 5146 comes with the 315 movement, are we absolutely certain that they have made the switch already?
Another odd thing; the Patek 5127 on a leather strap uses the 315 movement when the 5127/1 on a gold bracelet uses a 324 movement according to their website.
Many thanks in advance.
