I hate men's jewelry as much as men's cologne. The only jewelry I wear is a watch. I tried going with only my cell phone for a while but there are too many times when I am sitting in a class or at a table where digging into my pocket is a pain.
My daily watch, when motorcycle riding and around the house on days off; cheap, reliable, and not flashy, Timex Expedition Resin Case Camper Nylon Strap Watch
My new work watch, which I wear at the hotel, the Danish Skagen 233XLTMB Titanium Watch. Thin, subtle, and a great value.
I have a few other interesting watches, including one of the first Fossil watches, and a whole slew of the USSR Navy & Submarine watches. Those things were like wearing a brick strapped to my wrist
