I remember on the week of my wedding my fiance finally broke down and got something for his groomsman. He ended up getting them an antique pocket watch that we both knew nobody would ever actually use.

Their are more useful watches for guys out there.For example compass watches. Sometimes your Iphone 4 doesn’t know which way you are facing when walking. A compass watch is more accurate about telling you which direction is north or south vs your iPhone.
What about those guys that are military or at least like to play Call of Duty on their Xbox 360’s. What about a Timex military watch? Then when they are playing Xbox on live or out in the woods playing paintball, their groomsman gift will actually be useful for them. When was the last time you saw a man in his 20’s with a pocket watch?
Most groomsman typically attended college with the groom. In that case buy something that brings back memories of the old college days when all of you were single. Buy them college logo watch. For example, the nevada watch is both a nice stainless steel watch AND has your college logo. I’m sure that would bring back memories of how many times you ran off to Las Vegas when you should have been studying for those difficult exams.
Anyway you look at it, watches make great gifts for men. Another option would be to buy some Rolex replicas and make them think they are real. That only works if you have a well paying job though.
