Yup. Helium is such a tiny thing it can diffuse through almost anything, and in MEMS oscillators which are supposed to be at a rock solid 32kHz, causes variance in the frequency eventually just “gumming” it up entirely and causing it to stop working.

If you want to know how and why, Applied Science did a video on it. Five years ago. Because that’s when this leak happened.
