I am the new owner of two automatics, both with ETA 2824 movements. When I wear both, I can hear the ticking of the movement when the watch is within 9 inches or so of my ear (for instance, when I'm resting my head on my hand).
This doesn't bother me that much (in fact, it serves as a reminder to look at the sweet, sweet second hand on my Stowa Marine) but I'm curious: how much variation across watches and movements is there in this area? I read on one post that Rolexes are virtually impossible to hear. Any other data points?
