My watch has a titanium case and a leather strap. Weighs nothing.
I like the look. More of a silver-y man than a gold-y man. For a wedding ring though, I like my brothers, gold band, not particularly thick but a near hemispherical cross-section. It is gold, but I still like it. Might get one in platinum, then when my muscles waste with advanced age I'll get a lightweight titanium one - that is why you want titanium right?
