Overview
A precision mechanical stopwatch featuring a crisp white enamel dial and a rare 'Erreff' D.R.G.M. protective metal casing. This instrument was designed for high-stakes timing, likely for military or industrial use, where accuracy was a matter of life and death.
Story
Junghans was the world's largest clockmaker by 1903, but this piece hails from their era of wartime precision. The 'Erreff' case was a specialized armor designed to protect the delicate glass from the chaos of a battlefield or factory floor.
Maker / Origin
Founded in 1861 by Erhard Junghans, the company became a titan of German engineering and a pioneer in radio-controlled and quartz technology. During the mid-20th century, they were a primary supplier of chronographs and timing devices for the German military.
Condition & Value
The stopwatch dial appears clean, but the case shows significant wear, including tape residue on the back and a yellowed/damaged window in the protective cover. These signs of heavy use reduce the value by approximately 30% compared to a mint example.
