The first sighting of the bracelet in 1.01 Pilot.

Until early season 5, every sighting of Sam without long sleeves features a thin black bracelet on his right wrist. It has no known significance to Sam.

Fandom lore has it that the bracelet was reputedly a gift from Sandra McCoy to Jared. After their breakup in 2008, Jared continued to wear the bracelet for character continuity.
