Introduction

    • Insert a standard paper clip into the holes on both sides of the watch that connect the watch's face with the wrist strap.

    It may be easier to push the pins out in one direction. Unfortunately, I do not recall which direction was easier…

    • Apply an upward pressure to the holes until the locking pins release.

    • Use precision tweezers to remove the pins that connect the face with the strap.

  3. H2cHqYkHqackb2CH

    • Once the pins are released, the old wrist strap should snap off.

    • Simply lock the new wrist strap into place.

  4. S3W2H3WyphXWREQE

    • Use the T5 head on the iFixit screwdriver to unscrew the four screws on the back of the watch’s face.

    • Use tweezers to gently pry the golden sensor away from the battery.

    • Remove battery using the plastic opening tools.

    this shows how to take the battery out; what about replacing it nd securign the ‘electricity leads’ of the new battery to the watch?

    François Collet -

    Bonjour François, as tu réussi à remonter la batterie?

    Thierry Grandjean -

    Very strange you haven't completed the procedure.

    John Kirk -

    It says 'To reassemble your device, follow these instructions in reverse order' How difficult is that? So, put battery in, carefully fold contacts back, etc, etc....if that is not obvious, then please do not attempt this at all.

    • Attach a new screen to the screen protector.

    • Make sure that the charging port remains accessible, as it can easily become detached during the replacement.

    hello and thanks for the tutorial. I need to fix the screen of a V800 polar and I have a screen of the m400. Do you think I can replace one with the other? Can you confirm what the same LCD is? Thank you very much for everything

    Christos Dimitrakakis -

Polar won’t sell spare parts so where can I buy a replacement screen or a replacement front case for the M430?

Olivier Grand -

hello olivier,

did u find a resellor for polar spare pieces , i am looking for usb connector fo m400

Mathieu Poncet -

I destroyed the micro usb port on my watch (don’t ask..) I bought another used m400 for a very cheap price, because the screen protector was messed up - full of scratches. I switched the insides of the watches using your instructions. Thank you! I now have a working watch with a clean screen protector and an extra battery just in case I need one later.
