ZenWatch 2 comes in two sizes - 37mm and 41mm (width).
The smaller 37mm sports an 18mm strap, with the 41mm having a larger 22mm band. Both have AMOLED dipslays with Gorilla Glass 3, IP67 dust and water resistance, magnetic charging cables, and use unspecified Qualcomm processors (likely still a Snapdragon 400).
The ZenWatch 2 has a crown now, too, which ASUS says adds functionality, but isn't exactly specifying how just yet. It's also not clear if the smaller ZenWatch 2 has a smaller screen, or if the case is simply shrunk down a bit.
