Doomsday Clock is a direct sequel to Alan Moore’s The Watchmen and continues story elements from several other DC crossover events: Superman Reborn, The Oz Effect, and The Button. This ground breaking event will conclude the New 52 & DC Rebirth storyline.

Series creator Geoff Johns felt like there was "an interesting story to be told in DC Rebirth with Doctor Manhattan and Superman." Each comic in the 12 part maxi-series will feature two covers from artist Gary Frank and colorist Brad Anderson.
