In 1878 Moritz Grossmann, founder of the German Watchmaking School in Glashütte, wrote an article for the German Horological Journal describing design criteria and practical solutions for a precision regulator clock. 

Grossmann's explanations from 1878 form the basis for the design of the Ingénieur du Temps 3D printed clock. 

Important features such as the dial layout and the repartition of the gear train are taken directly from Grossmann's explanations resulting in a reliable and accurate clock that is esthetically pleasing. 

From that solid base modern 3D printing technology allows a playful execution of the design resulting in a very modern clock based on historical principals.
