SAFETY: Clock Choke from Invisible Collar targets the Carotid arteries and jugular veins. Tap early and often. Your safety is more important than any training round.
Defending the Clock Choke from Invisible Collar requires recognizing the threat earlier than a standard clock choke because the concealed grip eliminates the normal warning signs of collar establishment. In a standard clock choke, the defender feels the attacker reaching for their collar and can begin defense immediately. With the invisible collar variant, the grip is already deep before the walking motion begins, compressing the defensive timeline dramatically. The defender must develop awareness of subtle grip positioning changes during back control that indicate the invisible collar is being set up, and begin defensive action before the walking arc starts.
The primary defensive strategy focuses on stripping the collar grip with both hands before the walking pressure makes removal impossible. Once the attacker begins walking, the defender must combine aggressive two-handed grip fighting with directional hip movement away from the choking side. Understanding the attacker’s submission chain is critical—purely defending the collar often opens the defender to rear naked choke or bow and arrow transitions, so escape movements must account for multiple threats simultaneously.

How to Recognize This Submission
How do you know when someone is attempting Clock Choke from Invisible Collar?
- 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
Key Defensive Principles
What are the key principles for defending Clock Choke from Invisible Collar?
- 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
Defensive Options
What can you do to defend against Clock Choke from Invisible Collar?
1. Two-handed collar grip strip before walking begins
- When to use: As soon as you feel fingers penetrating your collar or detect the invisible collar setup during back control
- Targets: Invisible Collar
- If successful: Removes the primary choking mechanism, forcing the attacker to re-establish grip from back control
- Risk: Committing both hands to the collar leaves you temporarily vulnerable to rear naked choke if the attacker releases the collar and switches
2. Explosive sit-out toward the non-choking side during hook removal
- When to use: During the brief transition window when the attacker removes hooks to begin the walking motion
- Targets: Invisible Collar
- If successful: Creates enough space and angle change to turn and face the attacker, neutralizing the clock choke angle and potentially recovering half guard
- Risk: If the far-side anchor grip is solid, the sit-out may fail and you lose energy in an already compromised position
3. Roll toward the choking side and recover to closed guard
- When to use: When the walking arc has already begun and grip stripping has failed—last resort before the choke locks in
- Targets: Closed Guard
- If successful: Breaks the walking angle and transitions to guard where the collar grip becomes less dangerous without the walking pressure
- Risk: The roll can tighten the choke momentarily before breaking the angle, creating a brief window where you may be choked during the roll itself
Escape Paths
How do you escape Clock Choke from Invisible Collar?
- 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
Best-Case Outcomes for Defender
What is the best outcome when defending Clock Choke from Invisible Collar?
→ Invisible Collar
Strip the collar grip with two-on-one control and immediately work standard back escape sequences while the attacker must re-establish their grip. The grip removal eliminates the immediate submission threat and resets to a standard back control defense scenario.
→ Closed Guard
Execute a controlled roll toward the choking side when the walking arc creates enough momentum to carry through. Keep the chin tucked during the roll and immediately close your guard upon landing. While closed guard is a bottom position, it neutralizes both the clock choke angle and the back control entirely.
