The armor was made of beskar, a metal found on Mandalore, the homeworld of the Mandalorians, which made it almost indestructible. The Mandalorian helmet itself was unique to the Death Watch and consisted of a black, T-shaped visor with a complex heads up display.
Death Watch had their own version of Mandalorian armor made from beskar that originated from the mines of Concordia. Their rank insignia was located on the left shoulder armor plate.
Beskar was a material used by the various groups, clans and houses of Mandalore's people, such as the clans Wren, Vizsla, Saxon, and Kryze; and the Nite Owls, as well as the Children of the Watch.
What makes much of the armor in The Clone Wars different from Din Djarin's or Bo-Katan and her Nite Owl's is that it isn't pure Beskar. The Mandalorian makes a point of saying that he finds pure Beskar, which is the metal in its best and strongest state.

Did Darth Vader wear Beskar?
Darth Vader's armor isn't made of beskar, but of durasteel, allowing mobility and absorbing energy from lightsaber blows. Obsidian in the armor supercharged Vader's dark side power, turning anger into a power source.
(Fun fact: According to Star Wars canon, Phasma's armor isn't beskar either. It was actually made using scrap metal taken from Emperor Palpatine's old yacht.)
Yes, Boba Fett's armor is made of Beskar Iron like Mandalorian's armor. He inherited it from his father Jango Fett. His armor offers him strong protection against the Pykes and Cad Bane in the Book of Boba Fett.
Mandalorians View Beskar as Intrinsic to Their Culture
All of Gideon's Stormtroopers were wearing beskar armor, and Moff Gideon's Dark Trooper armor was also made of beskar. The fact that Gideon's armor was beskar was an insult in and of itself.
Cherished for its incredible strength and durability, beskar was notable for being able to withstand blows from even a lightsaber, and was commonly thought to be nearly indestructible, making beskar more prized than durasteel or cortosis.
From something as small as a pauldron, which Din once removed to ease Grogu to sleep in The Mandalorian season 1, to an entire suit of armor as Sabine is seen doing in Ahsoka, a Mandalorian is allowed to remove their armor.
Death Watch may have been exiled from Mandalore, but it did not stop them from showing the galaxy their ways of combat, which led them to Aq Vetina, where Death Watch saved a young Din Djarin from Separatist droids, and took him in as a Foundling.
Notably, the Dagoyan Masters of Bardotta regarded the Jedi as thieves and kidnappers because of that practice. Some Mandalorians, most notably members of Death Watch, held a grudge against the Jedi for their perceived crimes against Mandalore during the Mandalorian-Jedi War.
Jango Fett's armor was partly made of durasteel, and General Grievous had some parts of his body made of this material. Darth Vader's armor was mostly made of durasteel, as was Boba Fett's before he upgraded during the Second Galactic Civil War to armor made of beskar.
In contrast, Din Djarin's armor was made from pure beskar, earned through the bounty on Grogu. This made Djarin's armor rare and even more durable than normal Mandalorian armor, allowing it to stay shiny and undamaged even when he walked into a barrage of blaster fire.
It's possible that Gideon used the pure beskar from a fallen Mandalorian in order to craft his own helmet from scratch, or he just used it as is. It's also a possibility that Esposito's villain is using the same general helmet of a dead Mandalorian but made some alterations to it along the way.
The starfighters were produced during the war between the Galactic Alliance and the Confederation. The starship employed Verpine ultramesh technology to produce a lightweight frame made exclusively from beskar, which made the fighter durable and maneuverable in the atmosphere.
An ominous figure in gleaming gold stormtrooper armor, Commander Pyre leads the tenacious First Order forces on a mission to find a pair of refugee children on the Colossus platform.
Gwendoline Christie portrays Captain Phasma. The character's creation was inspired by a rejected design for Kylo Ren. Costume designer Michael Kaplan came up with the concept of Kylo being "the Lord of the Stormtroopers, in bright shining silver armor".
Affiliation. Boba Fett's armor was a suit of customized Mandalorian armor worn by Boba Fett, a human clone who became a bounty hunter. The armor was made from beskar.
One lightsaber strike cannot cut through the Mandalorian Beskar armor or a Beskar weapon. But if a lightsaber stays in touch with it for a longer period, it will melt it. It also depends on the wielder of the weapons. Jedis wield a lightsaber that is much stronger than a Mandalorian warrior.
