Jürgen Abeler has only very little information on Thomas Wolfgang Arnolt (circa 1640-1704); he gives his marriage date as 1678 and mentions that he died before 1704. Arnolt received the freedom of the city of Hamburg in 1662. He was a very able watchmaker. Few watches by him are known; one similar to the present watch is in the Hamburg Arts and Crafts Museum.
