The watch belonged to the former mayor of Zwickau, Johann Karl Keil (1861-1920).
Keil was a member of the Leipzig city council from 1896 to 1898. In 1898 he succeeded Lothar Streit as mayor of Zwickau (in the western part of Saxony) and held the position until he went into retirement on March 31, 1919 on his own request. From 1899 to 1918 Keil was also a member of the 1st chamber of the Saxon parliament, as 1st magistrate of the town of Zwickau. He was a board member of the art association and head of the honorary committee in Zwickau. Zwickau made Keil an honorary citizen in 1919 and named a street after him.
