Thanks for the housing-band reference!
This also happened to my wife's charge4 shortly after the end of the 1y warranty with more than half of the screw holders breaking off from the body.
I used superglue to reattach the connector part & its screws and it held up for a few months but now it broke off again.
Since she's not too thrilled about the look of the housing-bands, I'm considering drilling deeper into the existing screw holes and using longer screws (+glue) so it holds a bit longer. Anyone tried that? Any clue how deep I can drill beyond the side-surface of the watch body before hitting something important?
