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.

Attacking with the Clock Choke from Invisible Collar leverages the pre-established concealed collar grip to bypass the most difficult phase of a standard clock choke—getting the initial collar penetration without the opponent recognizing the threat. From the invisible collar position, the attacker already has deep four-finger collar control disguised as passive back control. The transition to clock choke finishing mechanics involves releasing hooks, shifting weight forward over the opponent’s shoulders, and initiating the circular walking arc that generates rotational compression against the carotid arteries. The key advantage is speed of onset—because the grip is already seated deep, the choke becomes dangerous within the first two steps of the walk rather than requiring the full arc to build pressure.

Key Attacking Principles

What are the key principles for executing Clock Choke from Invisible Collar?

  • 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

Prerequisites

What do you need before attempting Clock Choke from Invisible Collar?

  • Invisible collar grip established with four fingers deep inside the lapel and knuckles against the neck
  • Opponent in turtle or compressed posture with limited ability to track attacker’s weight shift
  • Free hand positioned to control the opponent’s far hip, belt, or pants for anchoring
  • Hooks removed or transitioning to sprawl position to allow walking movement around the head
  • Body weight beginning to shift forward over the opponent’s shoulders to load the choke

Execution Steps

How do you execute Clock Choke from Invisible Collar step by step?

  1. Verify Collar Depth: Confirm that your invisible collar grip has all four fingers deep inside the lapel with knuckles pressed firmly against the opponent’s neck. The thumb should be on the outside of the collar material. If grip depth is insufficient, use subtle wrist rotations to walk your fingers deeper before committing to the clock choke transition. (Timing: 2-3 seconds to verify and adjust)
  2. Establish Far Side Anchor: Reach your free hand across the opponent’s back to grip their far hip, belt, or pants waistband. This anchor prevents the opponent from rolling away from the choke direction and provides a fixed point for you to generate rotational pressure against. Secure this grip firmly before changing your lower body position. (Timing: 1-2 seconds)
  3. Remove Hooks and Sprawl: Disengage your hooks from the opponent’s legs and transition your lower body into a sprawl position with your hips driving forward into their upper back. This weight transfer loads the opponent’s shoulders and compresses their posture while freeing your legs for the walking motion. Maintain chest-to-back contact throughout. (Timing: 1-2 seconds)
  4. Initiate Walking Arc: Begin walking your feet in a tight arc toward the choking side, moving around the opponent’s head. Each step should drive your hip forward while your collar grip acts as the fixed pivot point. The walking motion creates a rotational tightening effect on the collar material against the carotid arteries without requiring you to pull the grip. (Timing: 2-3 seconds for initial arc)
  5. Drive Weight Forward and Down: As you walk past the opponent’s head, drive your chest weight forward and down into the mat, flattening the opponent’s upper body. Your shoulder should press into the back of their head or neck while the collar tightens from the opposite side. This creates a vise between your bodyweight pressure and the collar compression. (Timing: 1-2 seconds)
  6. Complete the Choke: Continue the walking arc until you feel the opponent’s body go slack or they tap. Pull your choking elbow toward your own hip to maximize the collar’s rotational pressure against the neck. Keep your far-side anchor grip tight to prevent any last-moment roll or escape. Maintain steady progressive pressure rather than explosive jerking force. (Timing: 2-4 seconds to finish)

Opponent Defenses

How might your opponent defend against Clock Choke from Invisible Collar?

  • Opponent grabs choking wrist with both hands to strip the collar grip (Effectiveness: High) - Your Response: Accelerate the walking motion to tighten the choke before the grip can be broken. If the grip starts slipping, immediately transition to a rear naked choke setup since both their hands are now occupied with your collar arm, leaving their neck exposed. → Leads to Invisible Collar
  • Opponent rolls toward the choking side to relieve collar pressure (Effectiveness: Medium) - Your Response: Follow the roll by maintaining your walking arc and keeping chest pressure connected. The roll often helps you by creating additional rotation on the collar. If they complete the roll to guard, maintain the collar grip and finish from top position. → Leads to Closed Guard
  • Opponent sits out and turns to face you during the walk (Effectiveness: Medium) - Your Response: Use your far-side anchor grip to prevent the sit-out from completing. If they partially turn, redirect your walking arc to follow their rotation and maintain the collar angle. The collar grip often becomes even more effective when they turn into it. → Leads to Invisible Collar
  • Opponent tucks chin aggressively to block collar from seating on carotid (Effectiveness: Low) - Your Response: The invisible collar grip is already beneath the chin from the initial setup, making a chin tuck less effective than against a standard clock choke. Continue walking and driving weight forward—the chin tuck is exhausting to maintain and the collar pressure builds regardless. → Leads to game-over

Common Attacking Mistakes

What mistakes should you avoid when executing Clock Choke from Invisible Collar?

1. 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.

2. 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.

3. 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.

4. Lifting hips too high during the sprawl transition instead of driving weight forward

  • Consequence: Reduces choking pressure and allows the opponent to flatten out and extend, creating space to escape or remove the collar grip
  • Correction: Keep hips low and drive them forward into the opponent’s upper back. Your weight should compress their shoulders downward, not float above them.

5. Pulling the collar grip away from the neck rather than rotating it against the neck

  • Consequence: Creates a crank or jaw pressure instead of a clean blood choke, reducing effectiveness and increasing injury risk without proper carotid compression
  • Correction: Rotate your choking forearm toward your own hip while maintaining knuckle contact against the neck. The collar should fold and tighten against the arteries, not pull away.

6. Abandoning back control too early before the choke mechanics are locked in

  • Consequence: If the choke fails, you have no dominant position to return to and the opponent recovers to a neutral or advantageous position
  • Correction: Maintain the option to return to invisible collar back control until the walking pressure is clearly generating choking response. Only fully commit to the clock walk when you feel the opponent’s posture compressing.

Training Progressions

How do you train Clock Choke from Invisible Collar (Attacker)?

Phase 1: Grip Transition Isolation - Invisible collar to clock choke grip mechanics Practice the grip transition from invisible collar back control to clock choke walking position with a compliant partner. Focus on maintaining collar depth during hook removal and weight shift. Perform 20 repetitions per side with no resistance, building muscle memory for the transition sequence.

Phase 2: Walking Arc Development - Walking mechanics and weight distribution With the collar grip established and partner in turtle, practice the walking arc at 25% resistance. Focus on keeping tight to the opponent’s head, driving weight forward, and coordinating the far-side anchor grip. Track how many steps it takes to generate tap-worthy pressure.

Phase 3: Transition Under Resistance - Full sequence with progressive resistance Start from invisible collar back control with partner providing 50-75% resistance. Execute the full transition from concealed grip to walking finish. Partner defends with grip fighting, chin tucking, and rolling attempts. Practice adjusting to each defense while maintaining choke integrity.

Phase 4: Live Positional Sparring - Competition application and chain integration Begin from back control with the goal of establishing invisible collar and finishing the clock choke within 90 seconds. Partner provides full resistance. If the clock choke is defended, practice transitioning to bow and arrow, rear naked choke, or returning to back control. Track finish rate across 10 rounds.
