To celebrate Black History Month, Apple has unveiled a brand new watch band for the Apple Watch. The Black Unity Braided Solo Loop contains 16,000 interwoven threads made from recycled polyester yarn and is inspired by Afrofuturism. In addition, the Apple Watch finally supports ray tracing, but only through a new watch face.
