The F-91W is (I think?) the same form factor as the A158W[1], which is an absurdly good looking watch for the price. It goes with everything, stylish yet unobtrusive. I often wear it instead of more expensive watches. If you're concerned about the band snagging arm hairs, it's only done it maybe twice in a year, way fewer than other economy metal bands.
If you prefer a "smoky" alternative, the A168WGG[2] has a gunmetal gray tint to the band, the face is blacked out with clear letters, and the illuminator only lights up the letters. However, the A168 is just slightly larger than the A158, so I don't know if the internal modules fit the same (but larger means more room, so, probably?).
(while I'm nerding out on watches: my workhorse/black band watch is a GA-B2100-1AJF[3]. pretty stylish for a G-Shock, and you get a ton of features for a non-smartwatch. the bluetooth model (vs cheaper models) has more contrasting face colors/tones so it works with more outfits.)
