The final broadcast (over DuMont) was on 7 August 1952.
During the first season (September to December 1951), this program was broadcast on ABC on Thursday nights between 9:30 and 10:00 PM EST. During the second season (March to September 1952), this program was broadcast on the DuMont network on Thursday nights between 9:00 and 9:30 PM EST, alternating in that timeslot with repeats of Fireside Theatre (1949). The show was sponsored by the Gruen Watch Co., a manufacturer of watches and clocks, thus the title.
Two kinescope recordings of the DuMont Network version survive at the UCLA Film and Television Archive, with the rest presumed to be lost.
