See it on AmazonMost guys own a watch and nothing else. These are simple pieces that look right with a T-shirt, and most come in a gift box so there's nothing left to wrap.
Leather for the low-key guy, a heavier chain for the one who wants it seen.
Easy first pieces. Each has a way to adjust the fit.
