Its members, under the leadership of Tor Vizsla, fought against Jaster Mereel's "True Mandalorians" during the Mandalorian Civil War. They opposed his reforms and wished to continue to be savage raiders. At least some of them, including Vizsla, wished to start a new Mandalorian War and conquer the galaxy. They wore unique helmets and were led by an "Overlord."
Ill-disciplined to the extreme, they were skilled warriors nonetheless, but constant in-fighting and the egotistical nature of Vizsla's leadership of the Death Watch was its downfall. When Jango Fett finally defeated Vizsla, the remaining members of the group scattered, and it ceased to have any influence on the galaxy. Whilst seemingly destroyed, the beliefs of the Death Watch remained amongst some Mandalorians.
After the formation of the Grand Army of the Republic, Fett created the Cuy'val Dar to train the clone commandos. Two of the Mandalorian trainers, Isabet Reau and Dred Priest attempted to ingrain the beliefs of the Death Watch by secretly forming battle circles in the bowels of Tipoca City. Jango Fett discovered the existence of the battle circles by viciously beating Priest. The two Cuy'val Dar would later attempt to resurrect the Death Watch as a means to repel the Imperial occupation of Mandalore.
During the war, a group of Death Watchmen operated on Concordia, one of Mandalore's moons, under the leadership of Pre Vizsla. This group commited acts of terrorism in Kalevala's capital of Sundari and would attempt to capture Duchess Satine Kryze, the leader of the New Mandalorian pacifists.
When Alpha-Ø2 resurrected the Mandalorians, he invited many former Death Watch members to join his Protectors. Other members took up base in the Death Watch Bunker on the forest moon of Endor, under the leadership of Teti Viba, before he was killed by an unknown raiding party.
In the early days of the Rebellion, a man wearing the armor of a Death Watchman was seen protecting Tungo Li during the hearing of Janek Sunber. Dred Priest led several fellow Mandalorians in an attempt that tried and failed to restart the Death Watch, as a means of fighting off the Empire.
As a child, Nashiak Llalik was impressed with the armors of this group. He read a lot about them and entertained his younger sister, Saren, with stories about those armors. As an adult, Saren regretted being separated from her brother, partly because she would have enjoyed those stories again.
In 40 ABY, Mandalore Boba Fett believed the destruction of the Death Watch was his father's lasting legacy for the Mandalorians. Walon Vau, a member of the Cuy'val Dar, was known to say the Death Watch was the only group he truly considered his enemy.
