Moritz Großmann Glashütte pocket watches rough age determination

For historical Moritz Grossmann watches from Glashütte, an individual dating is not possible without the specific watch. As a rough chronological guide:

• 1854–1870s: early pocket watches from Grossmann’s first creative period; rare and often with individual characteristics.
• 1870s–1890s: Glashütte precision pocket watches, often with elaborately executed movements and typical Glashütte design features.
• 1900–1910s: still pocket watches; precise classification depends heavily on the movement type, signatures, and numbers.
• 1920s until 1931: late production before the end of the original manufactory.

These are rough time periods, not a serial number-to-year table. Reliable, publicly accessible serial number lists for all Grossmann watches are not readily available; movement and case numbers as well as calibers must be checked together. Modern watches from the brand Grossmann Uhren, founded in 2008, do not belong to this historical production.
