As a burgeoning watch nerd, solar-powered atomic clock radio-sync models are currently the only thing I collect, and Casio consistently has the best implementation of the concept. There's a purity of purpose that smartwatches can only aspire to... I don't need to worry about charging it, I don't need to worry about setting it, I can just throw it on and go. It does exactly what it's supposed to do, no more, no less. Right now, I'm putting a lot of wrist time on a G-Shock GWX-5600-1JF, a Japan import G-Shock square that also features moon and tide graphs at the top of the display. Primarily meant for surfers, I gather, though my intended application is surf fishing. I also picked up a JaysAndKays NATO strap conversion kit:

A full-length NATO strap through both link pins and across the back of the case means I'm not at risk of losing the watch if something similar happens again.
In my cursory research, it seems like Citizen and Seiko solar atomic models don't automatically set daylight-savings time when using the WWVB clock signal? If that's consistently true, it's kind of a bummer... not having to worry about resetting for DST is a big advantage. When the time change comes around, I usually end up resetting all the other clocks and watches in the house off one of my Casios, right down to the second. Fun party trick. :)
