Abstract: The present disclosure discloses a magnetic silicone watchband, including a first watchband and a second watchband corresponding matched to the first watchband. An arc-shaped watchband head is provided at one end of the first watchband and is connected to the second watchband. A semi-circular magnet is provided at an upper end of the watchband head. A rectangular hoop is provided at the end of the second watchband and is corresponding matched with the first watchband. A mesh-shaped metal mesh belt is provided in the interior of the second watchband, and the metal mesh belt is magnetically attracted to the magnet. The present disclosure installs a magnet on the watchband head of the first watchband and installs a metal mesh belt in the interior of the second watchband, thereby realizing the arbitrary adjustment of the connection size between the first watchband and the second watchband.
