1- Islam forbids the Muslims to imitate the disbelievers, especially the Jews and Christians, but this prohibition does not apply to all their affairs, rather it applies to matters of their religion and things that are unique to them, by which they are known. 2- The Muslims have no need to imitate any of the other nations in matters of religious rituals and acts of worship. 3- The prohibition on imitating the disbelievers does not apply to the things that they do and invent from which Muslims may benefit. There is no sin on the Muslims if they share in that, rather the Muslims should be in the forefront of such things.

Muslim men cannot wear bracelets, whether they are of the type mentioned in the question or other types, and whether they are made of leather, metal or anything else.
