    That doesn't look like an easy repair: <https://felixwong.com/2021/10/how-to-repair-broken-garmin-watchband-pin-supports-ears/>

    Besides the suggestions in the above article, you might consider
    re-designing the pin arrangement. You don't really need to have a
    spring pin and roller. A stiff pin will work as well if you don't
    care about removing the band. Make sure the pin is stiff or at least
    high carbon spring steel. If you have a wire brush, just pull out ONE
    of the wire bristles.

    Since the case is already ruined, you might consider just gluing the
    strap to the case.

    If all else fails, make a replacement strap from Velcro. Form a loop
    around your wrist. Glue the watch to the strap in whatever manner
    looks best.




    I once snapped off a spring watch pin and drilled my watch
    through for .050" stainless wire (the skinny part of a 15-17
    butted spoke)

    That would disable the watche's sensory capabilities unless there was
    a large enough opening in the velcro so the sensors in the center of
    the backplate could contact the skin.

    I have two Garmin watches, a Fenix 5 that I wear on bike rides and a
    vivoactive 4 that I wear the rest of the time. I noticed that they guy
    who broke his was wearing it so tight that muscle expansion broke it.
    I very much dislike having a tight band around my wrist and my
    experience is that they don't need to be worn tight for them to work.
    I've replace the Garmin bands with bands that have velcro wrap
    closures so I can make incremental adjustments.

    Good point. The sensor area is best left uncovered by Velcro. Also,
    Velcro sandwiched between the wrist and the watch will likely be too
    thick and uncomfortable.

    The sensor area is fairly small. See photo in above URL. Just glue a
    thin strap to the area between the edge of the case and the circular
    edge of the sensors. Or, use an extra wide thin strap, that covers
    the entire bottom of the watch case, with a hole punched out around
    the sensors.

    If it were my watch, I would try to reconstruct the broken area using
    one of the moldable plastic epoxy putty products available. I don't
    have a suggestion as to which one is best. The watch band will
    probably be in tension while worn, so some internal reinforcement wire
    or wire mesh might be useful. I have a plastic welding kit that comes
    with a smalls supply of such mesh. <https://www.google.com/search?num=10&q=plastic+welding+mesh&udm=2>

    I bought a used case from ali express for $15 and will take it apart and
    see if I can get it fixed. It is worth the try and B7000 adhesive
    softens at a low temp. I watch the video of how it is done. I did call
    Garmin they can only offer me a %20 discount on a new product. I may
    take them up on it but right now some decent deals on a Garmin 945 and 745.

    The used case seems like a good way to fix the problem. It should
    also be the easiest.

    I'm not a big fan of B7000 adhesive. It's a pre-mixed resin adhesive
    that relies on the evaporation of the solvent to cure. The result is
    that it's not very viscous and tends to drip. Here's a discussion
    that might help:
    <https://www.quora.com/Which-glue-is-better-E6000-or-B7000> <https://www.quora.com/What-is-the-difference-between-E6000-F6000-B6000-B7000-and-similar-glues>
    None of these adhesives should be use for molding the missing pieces
    of the watch case. I shouldn't be making a recommendation without
    first knowing which type of plastic and filler is used in the watch
    case. Offhand, I prefer E6000 mostly because tolerates a large
    temperature range.

    Good luck.
