Are there any parts that are swappeable from the OLED model to LCD?

From what I understand, this is a bit more than just a screen upgrade. The Gamer's Nexus crew did a super in depth teardown that details some of the more technical aspects of the redesign. I don't think there have been any comparisons with regard to part intercompatibility yet, but I would expect something to that end eventually. But it might be that they do not contain any parts that are interchangeable.

Either way, it's a pretty interesting watch about the redesign.
