In January, Apple released watchOS 11.3 with a new Black Unity watch face for Apple Watch. To celebrate African Diaspora History Month in February, Apple introduced a new Black Unity collection.
The new version of the Unity Rhythm watch face features unique numbers created by intertwined threads of red, green, and yellow. When the user raises their hand to look at the time, the abstract paint strokes smoothly transform into clear numbers.
A recent report by The New York Times noted a new trend: more and more people are wearing Apple Watch on their feet instead of their wrists. This is a curious trend, and the article discusses several reasons why users choose to wear their smartwatch in this unconventional way.
