Changing the Bezel

To Remove the Bezel:

1. Press your index finger and thumb on both sides of the bezel, or press your palm against the entire bezel.
2. Rotate it counterclockwise at an angle (approximately 20 degrees) with a little force until it stops.
3. Pinch vertically with two fingers to lift and remove the bezel accessory.

To Install the Bezel:

1. Pick up the bezel. Align the marking point on the inside of the bezel with the marking point at the 12 o'clock position on the watch screen. The CMF by Nothing logo should be positioned at approximately the 7 o'clock position.
2. Lower the bezel horizontally onto the watch body and fasten it.

Precautions for Bezel:

• Avoid applying excessive force when disassembling or installing the bezel to prevent damage to the internal structure.
• When installing, ensure the bezel is horizontally seated before rotating to avoid damage.
• It is not recommended to wear the watch without the bezel attached, as this may scratch the skin or wear down the internal structure.
• Frequent disassembly and assembly can cause wear and tear, potentially leading to issues with tightening or loosening, which is considered normal. Please use reasonable frequency for disassembly and assembly to extend the lifespan of the bezel accessories.
