Abstract: This disclosure describes techniques and apparatuses for rotational alignment of a circular display and a circular lens. In one or more implementations, a display device, such as a smart watch, includes a circular lens assembly that overlays a circular display assembly. The display device includes at least two alignment points positioned along the perimeter of the circular display assembly that enable a machine vision system to rotationally align the circular display assembly to the circular lens assembly. At least one of the alignment points includes a target mark on the perimeter of the circular lens assembly that is viewable by the machine vision system through a corresponding alignment hole on the perimeter of the circular display assembly. The alignment hole is within a border region of the circular display assembly, but is sized and positioned so that it does not impact the structure of the circular display assembly.
