8H63  The Minitmaster Jr.

A 30-minute timer!  Sits on a shelf or stove or wherever you need a precise, short-period timing convenience.  Has an audible reminder signal.  Its case is of glistening white plastic with a quilted motif and a red numeral band.

The knob could either be white or red.

Sort of a Minutemaster-inspired, repro, quartz junk clock they were selling a while back.
