1.1" Full Color AMOLED Screen: Big, Bright, and Beautiful Intense colors, high resolution, and large dimensions make this AMOLED screen a treat for the eyes. Knowing youll want to wear OPPO Band all the time, weve protected its screen with a curved layer of strengthened, scratch-resistant 2.5D glass. Aesthetic Appeal and More Starting with the basic concept of an exercise band, we added on a Style Strap*. We innovatively incorporated a metal buckle, fusing two styles into one that would allow users to switch out the band as desired. The Style Strap can be flexibly adjusted in all directions and conforms closely to the wrist to ensure a good fit no matter how its worn.
