Another vote for the Citizen Eco-Drive - I wear mine daily & as previously mentioned, it works with a tux or with a t-shirt & shorts. I get complimented on it regularly!
I have a lot of watches. I get many compliments on my Nixon watches and have been happy with the quality. They have a variety of styles and prices. http://www.amazon.com/s/ref=nb_sb_s...rds=nixon+watches+men&sprefix=Nixon+w,aps,225
