Analysis of Marketing and Reliability were broadly level from about 1950 to the late 1960s. Domestic synchronous clock sales declined from the late 1960s onwards and never recovered. By 1980 it was all over. Analysis of possible reasons for the final decline in sales shows that this was due to the poor overall reliability of domestic s

Gallery of Synchronous Bedside Clocksthose that have survived. The large number of Smith clocks, an alarm clock and a time switch (31 %) and Temco clocks (29 %) is noticeable. A number of clocks etc. (31 %) have Art Deco cases, but there are few clocks with other identifiable artistic styles. Relatively few clocks etc. (13 %) are self

Gallery of Synchronous Movements satisfactory in service. The rotation speed of motors was a compromise. The most popular was 200 rpm, but this was not universal. Synchronous motors are not inherently self starting. Many clocks had manual start motors. Some had self starting motors, but reliability of self starting methods was som

Mapping Transition in the Pamirsbut assisted case designers. Materials used included solid wood, plywood, brass, pewter, glass, porcelain, stone, and Bakelite. Later, aluminium and Perspex were also used. Domestic synchronous clock cases were of four main types: mantel clocks, bedside clocks, wall clocks, and granddaughter clocks.
