What is Clock Choke in BJJ?

The clock choke is applied when your opponent is in turtle position. You grip deep on their far collar, place your knee near their hip, and walk your legs around them in a circular motion like clock hands. As you rotate, the collar tightens around their neck. It is one of the most effective attacks against turtle and is a staple in both BJJ and judo. The walking motion creates progressive tightening that is difficult to escape.
