The Japanese company Rhythm Watch Co., Ltd. was founded in 1950 and developed into an internationally recognized manufacturer of clocks and precision equipment. Its roots date back to 1946. Alongside traditional wall clocks, table clocks and alarm clocks, Rhythm became particularly well known for its electronic musical and melody clocks. From the late 1980s onward, the company introduced elaborately designed clocks under the Small World brand, featuring melodies, moving figures and electronic sound systems. Over the decades, the company expanded into electronic components and precision products. Since 2020, it has operated under the name Rhythm Co., Ltd.
