Goerz DF03 6x24 Triëder Binocle 1914
Goerz DF03 6x24 Triëder Binocle 1914

Goerz developed the DF03 (Dienstfernglas) in 1903 for the German Army; until 1908 the DF03 did not have more widely extended tubes, restricted by the Zeiss patent, which expired in that year. The pre-1908 DF03 had 21mm objective lenses, with tubes attached to the bridge with screw on brass plates; the new model was increased to 24mm objectives with bridge arms integral with the tubes. Later, the DF03 was produced by other optical manufacturers for example, Zeiss, Leitz and Rodenstock.

The left prism cover is marked “DF03 6 Fach” (6x) and within the Goerz trademark prism, “UF/12680/Dienstglas” (Service Glass); the right prism cover is marked “Triëder Binocle”, and within the Goerz prism logo, “CP/Goerz/Berlin. “UF 12680” is likely a military inventory number. I have seen “UF” described elsewhere as indicating “NCO” (Non Commissioned Officer) but I am sceptical about this. The serial number “288337” means a production date of 1914. The under edge of the upper right bridge arm is stamped “K” meaning it was passed for military service by the Spandau Weapons Inspection Commission. On the lower left prism housing is engraved “55R II. This may stand for the 2nd Battalion, 55th (6th Westphalian) Regiment which was subordinate to the 26th Infantry Brigade, part of VII Corps. This Corps spent the entire war on the Western Front.

The early WW1 leather case was designed as part of the webbing, attached to the belt and shoulder strap. Inside the lid are, as is usual, printed instructions for user maintenance of the binoculars. It is generally in very good condition although one of the side retaining straps is torn. Later in the war, shortages meant binocular cases were made of ersatz materials.

The company was founded in 1886 by Carl Paul Goerz, making mathematical instruments. They eventually started manufacturing cameras and binoculars. Described as “a thorn in the side of Carl Zeiss”, following financial difficulties post WW1, they were bought out by Zeiss in 1927.


Note the two dots over the first letter E in Triëder.. This is known as an e-diaeresis and is distinct from the German umlaut which is only used on Ä, Ö and Ü. The diaeresis performs the same function as in French, i.e. it separates two vowels, e.g the French No-ël. Thus Triëder is pronounced “tri-eyder” rather than “treeder”. The e-diaeresis is used in German chiefly for proper nouns.
