The Western Clock Company and The Seth Thomas Clock Company merged to become divisions of General Time Corporation. Seth E. Thomas, great-grandson of the original founder of The Seth Thomas Clock Company was the first Chairman of the Board of General Time Corporation until his death in 1932.

The company produced electric, battery or main spring movements with plastic or bakelite cases.

The name of Western Clock Division of General Time Corporation was changed to Westclox Division, the name that had been used for many years as a trademark on clock dials.

Westclox® and Seth Thomas® contributed to America's World-War II efforts by producing highly sophisticated items for the Army, Air Force, and Navy. It is interesting to note that some of America's newest aircraft carriers of that time had as many as 64 Seth Thomas® marine clocks, while some of the giant battleships carried a complement of 77. Seth Thomas® marine clocks were standard equipment on many types of fighting craft from PT boats and submarines up through merchant and naval ships of every description.

During the war, General Time Corporation continued to advertise its two brands in major publications even though clocks were not available for consumer purchase. Seth Thomas® ads focused on its production of marine clocks and actually showed a cut-away of a Naval vessel with detailed installation of Seth Thomas® clocks. Other creative advertising themes were used, such as "Betty goes shopping with shears", urging customers to cut out pictures of Seth Thomas® clocks to be purchased "when her ensign comes home". During the war years (1942-1945), American consumers were urged in Westclox® and Seth Thomas® ads to buy war bonds to support "our boys at the front".

Due to the shortage of metals during the war years, The Westclox Division and other domestic clock manufacturers produced a "War Alarm" for domestic use with a corrugated cardboard case.

The Seth Thomas factory was nearly destroyed by a major Connecticut flood. Many of its manufacturing facilities were relocated to General Time factories in Georgia, Illinois and other areas.

Westclox® pioneered the first Quartz movement in clocks, trademarked "Quartzmatic™". Both the Westclox and Seth Thomas divisions produced clocks with quartz movements. This technology provided clocks that are highly accurate and, under normal and consistent pressure and temperature, an accuracy of plus or minus one minute per year can be obtained. This technology was used in the Apollo space command module.
