Um, I've bashed my watch against concrete walls/pillars by mistake when I've brushed against them in garages etc. So yeah, actually it can be a common scenario.
I'm glad I ordered the SS model.
This.
I totally see the common issue will be dropping a watch on concrete or brushing up against a brick wall or building or something. You probably won't have many pocket issues unless you're really digging around for something. But I see environmental issues such as buildings, walls, etc being a more likely case...
