He was one of the most famous if not the most famous early chronometer makers working in Germany. While Altona was under Danish administration at the time, it was generally considered to be a German city and literature refers to Kessels as a German maker. After stays in London and Kopenhagen he worked with Abraham Louis Breguet in London and settled finally in Altona, where he opened his own workshop. The famous chronometer maker Winnerl of Paris - one of the teachers of Ferdinand Adolf Lange - worked with Kessels in Altona for a while.
