I'm interested in those as well. Let's hope the alarm is louder than on the only Seiko alarm movement I'm familiar with-- the 7T62. The alarm on that is so anemic it's useless. I can't here it even over normal (not loud) office noise-- and it sure won't wake up anyone. The alarm on the X-33 however will wake the dead-- or scare the crap out of you if you're not expecting it.
