Start with how you use your hands. A man who works at a desk can wear almost any gold band without worry; a man who lifts, builds or fixes things should lean toward a harder alloy and a finish that hides marks. Then think about width and profile, a rounded top for a traditional look or a flat one for a sharper line, and finally the fit inside, standard or comfort.
Gold also has a practical upside for a ring you never take off: the color is the metal's own, so there is nothing on the surface to wear through and replace.
14K gold contains 58.3 percent pure gold, and the extra alloy makes it harder and more scratch resistant, which is why it is the practical choice for a band worn every day. 18K is 75 percent gold, with a deeper, richer yellow, but it is softer and shows wear sooner.
On a wide men's band the color difference between the two is easy to see, so look at both side by side before deciding. If you are torn, think about how you treat your watch: if it is scratched, choose 14K.
If your partner wears yellow gold, a matching band makes the two rings look like a set in photos and on your hands. If her ring is white gold or platinum, yellow still works; the rings sit on different hands, so there is no clash to worry about, and the contrast can say something about each of you. If you want a link between the rings without matching metals, match the finish instead: two polished rings, or two brushed ones, read as a pair even in different colors. Shopping together?

High polish gives yellow gold its classic glow but shows every scratch. A brushed or satin finish has fine parallel lines and a softer sheen that keeps light scratches out of sight. Hammered gold, covered in small dimples, disguises everyday marks best and suits a more rugged style.
