What is the benefit for a Muslim in wearing a silver ring on his hand?

A man wearing a silver ring on his hand is among the permissible adornments. Some scholars considered it a Sunnah, but the correct view is that it is permissible, not a Sunnah, because the Prophet, peace and blessings be upon him, acquired it out of necessity, not as an initial act. The benefit for the Muslim from it is adornment, along with following the Sunnah according to the second opinion.
