The gasket is not intended to be ridged! It needs to flex as within it is a sensor so the watch knows it was touched. I personally haven’t had any issues when I was fixing the watch (I don’t any more). The issue I’ve have seen is people not cleaning the surfaces properly as well as touching the gasket adhesive. Any oils or dirt on the surfaces will cause the part not to adhere properly. Make sure you are using reagent grade solvents. The other issue is an old gasket which is not properly sealed can have its adhesive dry out.
