Coolest photography nerd watch ever!
I don’t wear a watch so I have no interest in getting one, but it’s a neat idea. No help for actual photography, but cool. Well, no help unless perhaps you’re trying to remember the whole f‑stops. I was going to suggest that I’d like a similarly-themed wall clock, but I have too few walls and plenty of clocks. Besides, I know my f‑stops already.
