Awesome article. Lots of awesome science went into its development.

Yes, learned some brand new things about common events! Very cool, there's something about tech at a convergence of aesthetics, science and history that is really awesome.

I did wonder about one bit though, which really was driven home by their speculation about trying to do it mechanically at the end:

>"However, as a fan of astronomical complications, I can't help but wonder if this sort of complication couldn't be realized in a mechanical wristwatch or pocket watch."

Does what the Apple Watch is doing require GPS? I sort of assumed that if it's showing true noon/midnight and so on it must also be taking into account the watch's physical location and calculating with that. As someone who knows little about mechanical watches, can this be done without that, or there mechanical complications that can take a manual location adjustment as an input or the like? It's amazing to consider the kinds of creative and impressive engineering and construction that has gone into mechanical computation though. On almost the polar opposite scale, it somehow reminds me a bit of the Ars article last year mechanical analog computers for warships ( https://arstechnica.com/information-technology/2020/05/gears... ).

I’d like to see what the watch face displays in far northern or southern latitudes on the summer and winter solstices.

The Apple Watch sub Reddit had folks close to or in the Arctic posting their watch faces around the 21st of December. I’d imagine the same were posted for summer solstice.

Does anyone know of a website/js remake of this watch face?

some years ago i played around with something similar: https://sa.lj.am/sun/

source is linked at the bottom. much of it was written in elm and i no longer understand how any of it works.

Wow this makes me want to buy an Apple Watch!

In the military knowing first-light and last-light, down to within a few minutes, is essential daily. I have an app on my phone that tells me sunrise and sunset, but as the article describes these aren't the same thing. I also have a very expensive top-of-the-range Garmin watch and even that just tells me the less useful sunrise and sunset, which makes me suspicious it's not as military as it markets itself as.

I don't know if anyone knows an app that gives first-light and last-light for the phone, so I don't have to buy a new watch?
