U-Boat Badge 1939 - with Diamonds

The U-boat War Badge was originally instituted during the First World War on February 1, 1918. It was awarded to recognize U-boat crews who had completed three war patrols. The badge was worn on the lower left side of the uniform and was oval shaped resembling a wreath of laurel leaves. A submarine lay across the center and the German State Crown (Reichskrone) was inlaid at the top center of the wreath.
On October 13, 1939, the U-boat War Badge was reinstituted again. It was very similar to the original badge with the exception of the imperial crown being replaced with a German Eagle above a swastika, and a more modernized submarine now facing towards the left was used. The new version was first made of bronze metal, with later ones made of zinc with a "gold wash".
