Timex Group B.V. is the parent of Timex Group USA, Inc. The latter is located in Middlebury, Connecticut, and began in 1854 as Waterbury Clock in Connecticut's Naugatuck Valley, known during the nineteenth century as the "Switzerland of America." Sister company Waterbury Watch manufactured the first inexpensive mechanical pocket watch in 1880. During World War I, Waterbury began making wristwatches, which had only just become popular, and in 1933 it made history by creating the first Mickey Mouse clock under license from Walt Disney.
