I was thinking about getting myself one of these, for a while:
It’s Casio’s flagship GPS offering, with a lot of features. A bit (OK, very) large on the wrist perhaps but solar-powered, which would be ideal for a long ride. It’s actually described as “solar-assisted”, because even in bright sunlight, it won’t keep going forever while it’s tracking. But obviously it will run down a lot more slowly. I also really like the high resolution LCD screen.
The bummer though, and what stopped me buying one, is that there’s no way to export your track from the watch. You can upload it to Casio’s app and share it from there, but there’s no way to get it to Strava (for example) – or indeed anywhere else out of Casio’s ecosystem. Surprising.
