LOL. I've been wearing my Eco Zilla at work for the last few weeks. It's so rugged and water proof and I work in a water plant. It's a natural. I DO think my left bicep is getting bigger though.Wore my Citizen Eco Zilla all day today. I also like my Seiko SKX-007 automatic. The Seiko doesn't get a lot of wrist time, due to me not wanting to ding it up too bad at work.
