Hamilton Twilight/Sunset-question about complication

[Alathea]

Can someone please explain what the point is of a watch complication that tells the time of sunset in 6 cities on the 15th of the month? I love the look, and I own two other Hamiltons, but I guess im missing something about this one. What use is it, or what am I not getting?

Its like the moon phase or even for aome the chronograph function.

I had a Sunset a while back. Beautiful watch but that really is a useless feature. Once I found the spot that I thought the inner bezel looked best I never moved it.
I seem to remember reading that it could be used by pilots so they could know when they were flying into the setting sun or something like that. I think it is mentioned in the owners manual.

I have a Sunset as well and did the exact same thing. The OP is correct is his description of the complication. It is one of the more gimmicky functions out there but what the hell, it's a great looking watch.
