Abstract: An in-the-wall clock attachable to a preconstructed wall, and partially inserted into a hole in the wall, gives the appearance of having been inserted from the back of the wall prior to construction of the wall. This is effected by means of a ring, preferably a clock time ring, in conjunction with a back plate behind which the clock mechanism is placed. The back plate is surfaced in a similar manner to the wall. The face ring is positioned to mask the edge of the back plate, the combination of time ring and back plate concealing the wall hole. Thus the illusion is created that the clock mechanism was pre-built in the wall prior to final construction of the wall, and that the time ring was subsequently attached to the intact wall to delineate the clock face, or provide the clock numerals.
