I can remember going over to a girlfriend's house and laying the watch on her night table, it was glass covered, in the middle of the night she wakes me up about a strange sound, it was the danged watch vibrating on the glass table top. They were great watches, a little on the clunky side but not as bad as most diver type watches.
