Have you ever tried Creed's Royal Water? I don't know how it's possible, but citrus, especially verbena is very prominent throughout it's long lifespan. I guess because it's highlighted with peppermint which keeps the fresh aspect of it alive. Nothing lasts 12 hours on me, but this lasts about as long as anything. It's a safe wear, conservative yet uplifling in the impression it gives, great for summer, and has enough interesting notes (particularly some kind of grain and vegetal notes) to keep it from being boring. It's not especially manly, and to me is right in the center of the unisex spectrum.
For a pure orange that has a much longer lifespan than most, but shorter than Royal Water, Aqua di Parma's Arancia is excellent.
