Imperial Russian Submarine Officer's Qualification Badge, 1909.

Imperial Russian Submarine Officer's Qualification Badge, 1909. This historically significant qualification badge represents the elite cadre of the Imperial Russian Navy's submarine fleet following the award's formal establishment in 1909. The symbolic composition features a meticulously detailed stylized submarine hull superimposed upon a vertical anchor, centered within a circular border comprised of heavy nautical chain links and an inner rope-textured ring. Executed in silver with a rich, aged patina, the badge exhibits refined casting and chasing techniques that emphasize the structural elements of the vessel and the tension of the surrounding chain. The reverse of the decoration retains its original and robust screw-back mounting system accompanied by a large circular securing nut, characteristic of high-quality military appointments from the early 20th century. The badge measures approximately 40 mm in diameter. The item is in good condition.
