SAFETY: Clock Choke targets the Carotid arteries and jugular veins. Risk: Carotid artery compression leading to loss of consciousness. Release immediately upon tap.
The Clock Choke is a highly effective gi-based blood choke primarily executed from turtle position, though it can also be applied from back control variations. The technique derives its name from the circular walking motion the attacker makes around the opponent’s head, resembling the movement of clock hands. This submission targets the carotid arteries using a combination of the opponent’s own gi lapel and precise body positioning. The Clock Choke represents an excellent example of using the gi as a force multiplier, creating a mechanical advantage that doesn’t require significant upper body strength. The technique is particularly valuable because it can be executed when traditional back takes are defended, offering an alternative finishing option from turtle and transition positions. Many practitioners overlook the Clock Choke in favor of taking the back, but experienced grapplers recognize it as a high-percentage finish that capitalizes on the opponent’s defensive posture in turtle.

Safety Guide
Injury Risks:
| Injury | Severity | Recovery Time |
|---|---|---|
| Carotid artery compression leading to loss of consciousness | High | Immediate recovery if released promptly; potential for serious injury if held after unconsciousness |
| Neck strain or cervical spine stress from rotational pressure | Medium | 3-7 days for minor strains; 2-4 weeks for more severe cases |
| Jaw or temporomandibular joint (TMJ) compression | Medium | 1-2 weeks for minor discomfort; longer for existing TMJ issues |
Application Speed: SLOW and progressive - 3-5 seconds minimum to allow partner to recognize the choke and tap
Tap Signals:
- Verbal tap or verbal submission signal
- Physical hand tap on attacker’s body or mat
- Physical foot tap on mat
- Any rapid or frantic movement indicating distress
Release Protocol:
- Immediately release the lapel grip upon receiving tap signal
- Remove your weight from opponent’s back and create space
- Allow partner to recover in a neutral position without pressure
- Check on partner’s condition before continuing training
Training Restrictions:
- Never apply the choke rapidly or explosively in training
- Never maintain pressure after partner taps or shows distress
- Always ensure partner has clear access to tap with hands or feet
- Avoid training this technique with partners who have neck injuries or cardiovascular conditions
Outcomes
| Result | Position | Probability |

| Failure | Turtle | 27% |
| Counter | Closed Guard | 15% |

Playing as Attacker
Key Principles
-
Control the near side collar deep with full grip before initiating the choke
-
Walk your feet in a circular path around opponent’s head to create rotational pressure
-
Keep your hips close to opponent’s body to prevent escape and maintain pressure
-
Use your chest and body weight against the back of opponent’s head to seal the choke
-
The choking pressure comes from the rotation and body positioning, not arm strength
-
Maintain base throughout the circular motion to prevent counter-sweeps
-
The opponent’s own shoulder acts as the secondary pressure point against their neck
Execution Steps
-
Establish collar grip: From turtle position or while opponent is defending back control, feed your hand deep into opponent’…

Control far side: With your free hand, reach over opponent’s back and establish control of their far side hip, belt, o…

Begin walking motion: Start walking your feet in a circular path around opponent’s head, moving in the direction of your c…
-
Increase rotational pressure: As you continue walking, your body rotation creates increasing pressure on opponent’s neck. The comb…

Final adjustment and squeeze: Once you’ve achieved maximum rotation (typically when you’re past perpendicular to opponent’s body),…

Secure the finish: Maintain all pressure points: collar grip, chest pressure against their head, hip pressure against t…
Common Mistakes
-
Insufficient collar grip depth before beginning the walking motion
- Consequence: The choke has no structural foundation and opponent can easily defend or escape regardless of your body positioning
- Correction: Always prioritize getting a deep four-finger collar grip before attempting to walk. Your hand should be fed so deep that your forearm is across the side of opponent’s neck. If you cannot achieve this depth, use collar grips or hand fighting to create the opening.
-
Walking too quickly or taking large steps around opponent’s head
- Consequence: You lose base and balance, allowing opponent to counter-sweep or escape. Rapid movement also prevents smooth pressure application.
- Correction: Take small, controlled steps maintaining constant contact with opponent’s body. Your movement should be smooth and deliberate, like a controlled rotation rather than scrambling. Keep your center of gravity low and over opponent throughout the motion.
-
Failing to control opponent’s far side during the rotation
- Consequence: Opponent can roll away from the pressure, escaping the submission entirely and potentially sweeping you in the process
- Correction: Always maintain control of opponent’s far hip, belt, or far collar with your free hand. This connection is crucial for preventing the roll escape. Your chest pressure on their back also helps prevent rolling.
Playing as Defender
Key Principles
-
Protect the collar by keeping chin tucked and using your near hand to block or strip the collar grip before it sets deep
-
Recognize the Clock Choke threat early - the moment you feel a hand feeding into your collar from turtle, begin defensive action immediately
-
Create distance from the attacker’s chest by posturing up or driving away before they seal chest-to-head pressure
-
Disrupt the walking motion by moving your body in the same direction as the attacker, removing the rotational leverage they need
-
Address the collar grip as the primary threat - without it, the choke cannot function regardless of body positioning
-
Use explosive positional changes (sit-out, granby roll, stand-up) during the transition phase before the choke locks
-
Never remain static in turtle when a Clock Choke is being set up - constant movement prevents the attacker from establishing the sequential control points they need
Recognition Cues
-
Attacker’s hand feeds deep into your near-side collar with palm-down grip, placing their forearm blade against the side of your neck - this is the foundational grip for the Clock Choke
-
Attacker begins walking their feet in a circular path toward your head while maintaining chest pressure on your back - the walking motion is the signature tell of this submission
-
Attacker controls your far-side hip, belt, or collar with their free hand while their body shifts from behind you to beside you - this dual control signals imminent rotational pressure
-
You feel increasing rotational pressure on your neck as the attacker’s body passes perpendicular to your spine, with their chest driving into the back of your head
Escape Paths
-
Sit-out to guard: Turn your hips through toward the choking arm side, facing the attacker and pulling them into closed guard or half guard where the Clock Choke is neutralized
-
Granby roll to guard: Invert underneath the attacker in the opposite direction of their walking motion, using the momentum to recover guard and break the rotational pressure
-
Explosive stand-up: Drive through the attacker’s pressure with a wrestling-style stand-up, breaking the ground-based rotational mechanics that the Clock Choke requires
-
Turn into attacker: Rotate your body to face the attacker directly, accepting temporary guard position to completely neutralize the back-access requirement of the Clock Choke
