The present timepiece is believed to be the only known carillon minute repeating watch made by Julius Assmann or by any other of the celebrated German manufacturers of the period.

The carillon repeating mechanism is more complicated than the normal minute repeater and is usually found in clock watches. It features three or four gongs instead of only two.

Julius Assmann was born on 2 October 1927 in Stettin, Germany. After a watchmaking apprenticeship in his hometown, he went to Berlin to further his education.

In 1850 his travels brought him to Glashütte where he joined the watchmaking shop of F.A. Lange, who had laid the cornerstone of the German watchmaking industry in Glashütte in 1845. After only two years of employment the 25-year old Julius Assmann founded his own company, the Julius Assmann Deutsche Präzisions-Taschenuhren-Fabrik. His son Paul joined the business as a partner in 1877 and took over the management of the company after Julius died in 1886 at the age of only 58.

The watches made by the Assmann factory are renowned for their quality and obtained various awards and gold medals at international exhibitions. The highlights of the company included, among other things, chronographs with striking work and minute repeating as well as an "eternal calendar".

In 1926 Paul Assmann's son Fritz took over the management of the company now called Julius Assmann GmbH.

Around 1930 the firm was divided up among family members. The Glashütte Uhrenbetrieb acquired the rights to the traditional name Julius Assmann in 1945. Consequently, the company is able to name a watch after Julius Assmann, which meets the highest demands of watchmaking in every respect.
