SAFETY: Clock Choke from Invisible Collar targets the Carotid arteries and jugular veins. Risk: Carotid artery compression leading to loss of consciousness. Release immediately upon tap.
The Clock Choke from Invisible Collar combines the deceptive grip concealment of the invisible collar position with the rotational finishing pressure of the clock choke. Unlike the standard clock choke from turtle top where the attacker must first establish a collar grip, this variant begins with the grip already hidden deep in the opponent’s lapel from back control. The attacker transitions from concealed collar control into the characteristic circular walking motion, using the pre-established grip depth to generate immediate choking pressure before the opponent recognizes the threat has shifted from positional control to active submission.
This variant is particularly effective because the invisible collar grip disguises the clock choke setup as routine back control maintenance. The opponent allocates defensive resources to preventing rear naked chokes and armbar entries, leaving the collar grip unchallenged until walking pressure begins. The transition from invisible collar to clock choke finishing mechanics requires precise timing—the attacker must shift their weight forward and begin the walking arc at the exact moment grip depth is sufficient to generate carotid compression through rotation alone.
In competition, this technique punishes opponents who prioritize hook defense over grip monitoring. The invisible collar establishes choking infrastructure while the opponent focuses on removing hooks or preventing the seat belt switch. When the attacker initiates the clock walk, the choke tightens rapidly because the collar material is already seated against the carotid arteries rather than needing to be drawn across the neck during the walk itself.

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 |

Playing as Attacker
Key Principles
-
Maintain invisible collar grip depth throughout the transition from back control to walking position
-
Shift weight forward progressively to load the opponent’s shoulders before initiating the walk
-
Use the free hand to control the far hip or belt to anchor against the opponent’s escape direction
-
Walk in a tight arc toward the choking side to maximize rotational collar pressure
-
Keep chest connected to the opponent’s upper back during the entire walking sequence
-
Time the walking initiation for when the opponent is focused on hook defense or posture recovery
-
Accelerate the walk smoothly rather than jerking to prevent the opponent from recognizing the shift
Execution Steps
-
Verify Collar Depth: Confirm that your invisible collar grip has all four fingers deep inside the lapel with knuckles pre…
-
Establish Far Side Anchor: Reach your free hand across the opponent’s back to grip their far hip, belt, or pants waistband. Thi…
-
Remove Hooks and Sprawl: Disengage your hooks from the opponent’s legs and transition your lower body into a sprawl position …
-
Initiate Walking Arc: Begin walking your feet in a tight arc toward the choking side, moving around the opponent’s head. E…
-
Drive Weight Forward and Down: As you walk past the opponent’s head, drive your chest weight forward and down into the mat, flatten…
-
Complete the Choke: Continue the walking arc until you feel the opponent’s body go slack or they tap. Pull your choking …
Common Mistakes
-
Initiating the walk before the collar grip has sufficient depth
- Consequence: The choke lacks finishing pressure and the opponent easily strips the shallow grip during the walking motion, losing both the submission and positional advantage
- Correction: Verify four-finger depth with knuckles against the neck before removing hooks. If uncertain, continue working the invisible collar grip from back control until depth is confirmed.
-
Walking too wide an arc instead of staying tight to the opponent’s head
- Consequence: Creates space that allows the opponent to sit up, turn, or shoot underneath for a single leg, breaking the choke angle entirely
- Correction: Keep your chest connected to the opponent’s upper back and walk in the tightest possible arc, with each step driving your hip forward rather than stepping laterally away.
-
Neglecting the far-side anchor grip on hip or belt
- Consequence: Opponent rolls away from the choking pressure freely, escaping to guard or creating enough space to turn and face the attacker
- Correction: Establish a firm anchor on the far hip, belt, or pants before beginning the walk. This grip is as important as the collar grip for preventing defensive rolls.
Playing as Defender
Key Principles
-
Monitor the attacker’s over-hook hand position constantly for any collar contact during back control
-
Commit both hands to collar grip removal the moment choking pressure is detected
-
Tuck chin aggressively to limit the collar’s ability to seat against the carotid arteries
-
Hip escape away from the choking side to reduce rotational pressure angle
-
Prioritize surviving the choke over maintaining turtle—accept guard recovery as a win
-
Time explosive escape attempts for the moment the attacker removes hooks to begin walking
-
Maintain breathing discipline to avoid panic and premature energy expenditure
Recognition Cues
-
Attacker’s over-hook hand migrating from shoulder toward your collar during back control
-
Feeling fingers penetrating inside the gi collar material near your neck while opponent maintains back position
-
Attacker beginning to remove hooks and shift weight forward over your shoulders in preparation for walking
-
Sudden increase in forward pressure compressing your posture while one hand remains fixed at your collar
-
Attacker’s free hand reaching across to grip your far hip or belt, establishing the anchor for walking motion
Escape Paths
-
Two-handed grip strip to collar removal, then standard back escape to half guard or turtle recovery
-
Sit-out during hook removal transition to face opponent, recover to seated guard or clinch
-
Roll toward choking side to break walking angle, recover closed guard from bottom position
