08 happened November 1900: Established the Cross by length of service

08/11/14

The seniority-of-service cross minted in gold surmounted by the royal crown for officers who have served active duty for 40 years or more; in gold without a crown for officers who have served for 25 years or more and in silver for troopers who have served in the Army and Navy for 15 years or more.

The cross will be carried hanging from a green silk ribbon intertwined with a white list on the pole (in heraldry, an honorable piece that occupies vertically the third of the middle of the shield). Decoration still in use today, with variations in frills due to the change in the institutional regime of the 1946.
