I'm disappointed to report that within a week of buying a Citizen Eco-Drive BM8180-03E, a significant number of scratches have appeared on the crystal. It hasn't even seen hard use yet. Considering that I am a wildlife biologist who spends a lot of time in the outdoors, I do not expect it to last long. Especially when I start using it for work.
It may look like a rugged outdoor watch, but it doesn't appear to work as one. My impression is that this is a watch made to look outdoorsy but not to actually function in outdoor conditions.
