Would you buy a watch with a complication or function you don't expect to use from time to time?
I had to get a new watch recently and the watch i like the best, with regard to looks, had a tachymetre bezel. I've tried to find any use for it but failed. This sealed my decision not to buy it. I got a watch where i liked its look less, but lacked unused complications while it offered two aspects i greatly appreciate.
A similar thought ruled out some digital watches with tide display. I'm just not often enough at the sea to accept having to look at it 100 or 200 times a day to maybe use if for a fortnight every couple of years.
