Microsoft developed an unreleased smartwatch called Moonraker, codenamed LS-50, designed to run on Windows OS with a Modern UI. It was intended to launch alongside the Lumia 930 but was canceled after Microsoft's acquisition of Nokia's devices and services division. Prototypes were showcased at Mobile World Congress, but the device never reached consumers. Recent images of the Moonraker were shared by Microsoft design employee Pei-Chi Hsie on Tumblr before being removed.
