Original Item. Only One Available. This is an original German WWII 6x30 Dienstglas military binocular set manufactured by Swarovski at Wattens, Tyrol, and accompanied by a black Bakelite carrying case. The binoculars retain their wartime tan-painted finish, brown eyecups, textured body covering, and leather neck strap. The left prism cover is stamped with the three-letter manufacturer code cag, identifying Swarovski production, together with the blue triangular cold-weather lubricant marking.

The opposite prism cover is marked:

Dienstglas translates literally as "service glass," the designation used for German military binoculars. The 6 x 30 designation specifies 6-power magnification with 30 mm objective lenses. The H/6400 marking denotes the provision for a graduated Strichplatte, or optical reticle, based on the German 6,400-mil angular system.

The binoculars retain their hinged central bridge, independently adjustable eyepieces, brown molded eyecups, leather-covered barrel sections, and original-style leather carrying strap. The included black Bakelite case has a hinged lid, metal front closure, side suspension rings, and interior retaining straps.

The set is in good overall condition with substantial service and age wear. The tan finish remains extensive but has chipped and worn through along exposed edges, the objective rims, bridge, and other high-contact areas. The textured barrel coverings remain substantially intact. The leather strap is aged and worn but remains present. The optical elements show internal haze or clouding, particularly noticeable in one optical path, and the binoculars are therefore offered as a historical collectible without any representation regarding optical performance. The Bakelite case remains solid, with surface scuffing and wear, oxidation to the metal fittings, and age deterioration to portions of the leather components. No shoulder strap for the case is included.

Historical Context

The 6x30 Dienstglas was among the most widely used optical instruments in the German armed forces during WWII. Its six-power magnification provided a practical balance between image stability, field of view, and portability, making it suitable for observation during mobile operations. These binoculars were issued across the Wehrmacht, particularly to officers, NCOs, reconnaissance personnel, artillery observers, and soldiers responsible for identifying distant positions and monitoring enemy activity.

For infantry officers and reconnaissance personnel, binoculars were essential for studying terrain, locating potential threats, and directing troop movements. Artillery observers used them to identify targets and observe the results of gunfire, while forward personnel relied on them to examine defensive positions and identify landmarks. Their relatively compact size allowed them to be carried throughout extended field operations, making the 6x30 configuration particularly useful in situations requiring frequent observation while on the move.

The Swarovski firm of Wattens, Austria, was among the manufacturers involved in supplying optical equipment to the German military. Wilhelm Swarovski had developed a 6x30 binocular in 1935, drawing upon the precision glassworking techniques established by the family business. Following Austria's annexation by Germany in 1938, the Wattens facilities became involved in German military optical production. Wartime manufacturing codes allowed the authorities to identify individual suppliers while simplifying the identification markings applied to military equipment. Swarovski received the three-letter code cag, which is closely associated with its wartime binocular production.

German military binoculars frequently incorporated an internal graduated reticle, known as a Strichplatte, which permitted observers to estimate distances using angular measurements. The H/6400 designation refers to the German military system dividing a complete circle into 6,400 angular units, or Strich. By comparing the apparent height or width of an object against the reticle graduations, an observer could estimate its distance when its approximate dimensions were known. This was particularly useful for reconnaissance and artillery observation, where accurate distance estimates and clear communication of target positions were important.

Cold-weather performance also influenced the manufacture and maintenance of German military optics. The severe conditions encountered during operations on the Eastern Front exposed difficulties with lubricants that became excessively stiff at low temperatures. Special cold-resistant greases were adopted for optical instruments, allowing their adjustment mechanisms to remain usable during freezing weather. The blue triangular marking introduced for such equipment indicated that the instrument had received the appropriate lubricant.

During the later years of the war, German military equipment increasingly appeared in tan or sand-yellow finishes. Although these colors originated in part from camouflage requirements in arid environments, their use extended into European operations following the end of the North African campaign in May 1943. By this period, equipment production and finishing practices had become increasingly standardized around colors suitable for a variety of operating environments.

Military binoculars remained important throughout the war, even as reconnaissance aircraft, radio communications, and other observation technologies developed. Individual commanders and forward observers still depended on direct visual information when making immediate tactical decisions. The 6x30 Dienstglas fulfilled this requirement as a portable optical instrument suitable for routine observation, reconnaissance, and battlefield coordination.
