Friedrich Vetterlein Glashütte Chronometer Age Determination
Share
- Carl / Karl Vetterlein (ca. 1860 – 1930) was a precision mechanic and master watchmaker in Glashütte i/Sa.
- He was a graduate of the German Watchmaking School Glashütte (DUS) and later a teacher there.
- Active from about 1880 to 1925 .
- His workshop produced high-precision observation watches, marine chronometers, precision pendulum clock movements and pocket watches .
-
Engravings usually as:
“Vetterlein Glashütte i/Sa.”
or “C. Vetterlein Glassworks”
These pieces were unique creations or small series of extremely high quality, comparable to Strasser & Rohde or Ludwig Strasser.
Typical watches & movements
| Period | Typical watches | Special features |
|---|---|---|
| 1880 – 1895 | Precision pendulum clocks, pocket watches | Signature “Carl Vetterlein Glashütte” , finely engraved work bridges, handcrafted |
| 1895 – 1910 | Marine chronometer / Table chronometer | High-precision compensation balances, precision escapement |
| 1910 – 1925 | Small series of technically very sophisticated precision pocket watches | Engravings on the works, mostly elegantly hatched, "Vetterlein Glashütte i/Sa." |
Age determination by serial number
Unfortunately, the Vetterlein serial numbers are not fully published, as there were only around 100-200 individual productions .
However, based on well-known museum and auction pieces, guideline values can be given:
| Serial number (approx.) | period of origin | note |
|---|---|---|
| Nos. 1 – 30 | ca. 1880 – 1890 | Early phase, partly school or exam clocks |
| Nos. 30 – 70 | ca. 1890 – 1900 | Signature “Carl Vetterlein Glashütte i/Sa.” |
| Nos. 70 – 120 | ca. 1900 – 1910 | Ultra-fine precision or marine watches |
| Nos. 120 – 160 | ca. 1910 – 1920 | Late work, improved regulation |
| Nos. 160 – 200 | ca. 1920 – 1925 | Final phase before the company's demise |
Features for dating without known series
| feature | Chronological context |
|---|---|
| Hand-engraved signature in cursive script | before 1900 |
| Block capitals with “i/Sa.” | ca. 1900–1925 |
| Visible compensation balance wheel with swan-neck fine adjustment | after 1895 |
| Very fine bridge shape, gold chatons, blued screws | typical 1900–1920 |
| Nickel or silver circuit board (gold-plated) | around 1910 |
Glashütte chronometer makers
Friedrich Vetterlein was born on November 26, 1881, in Lübtheen. In 1901, Vetterlein attended the German Watchmaking School in Glashütte and produced a chronometer movement model with the number 1347 and an anchor tourbillon movement model with the number 1374.
During his training at the German Watchmaking School in Glashütte from 1914 to 1915, Vetterlein, a student of Gustav Hesse, built a tourbillon with fusee and chain . He employed a novel design in which the escape wheel was located under the base of the rotating carriage .
Helwig later described this clock in his book "Drehganguhren" (Rotary Gear Clocks) . With this, Vetterlein created the prerequisites for the floating-mounted rotating carriage , as later developed by Alfred Helwig .
In 1915 he developed the Vetterlein's Rider, named after him.
Vetter was a member of the Saxonia fraternity and resided at Friedrichstrasse 89b in Berlin around 1938. He initially worked for the A. Lünser company in Berlin and later became a legendary chronometer maker in Glashütte.
