This watch was produced in Friedberg; Johann Georg Wagner, however, added the designation “London” to his signature like an English maker would, to achieve a higher sales price.
In addition to Wagner, there were another 24 makers in Friedberg at the time whose names can be found with a fake designation such as Paris, London or Augsburg.

Johann Georg Wagner was born in Mulhouse in 1714; he married in Friedberg in 1746 and died there in 1791.
