The Versa 2 retains that rounded-square case design that the original Versa had, only now it has a new AMOLED display, one side button, and an improved processor. The AMOLED panel gives the watch a higher-quality look and feel with deeper blacks and more vibrant colors. Images should also look crisper, and indeed the photos used in the Exercise app appear to have more detail than they did before. But Fitbit OS doesn't use too many photographs, so you'll mostly enjoy the improved screen through the operating system's color iconography.
