Adolf Kittel (1845-1921) was one of Germany's foremost maker of pendulum clocks and pocket and marine chronometers which regularly exceeded at Observatory trials. He was the watchmaker of confidence of the Hamburg Observatory which owned several of his clocks and chronometers. Kittel became the first teacher at the Altona Horological School (1878-88), later known as the Hamburg Horological School.

The engraved inscription "U.S.C. & G.S." probably stands for "U.S. Coast & Geodetic Survey", now National Geodetic Survey, a United States Federal Agency, amongst others in charge of mapping and charting and a large number of applications of science and engineering.
