I like the idea of this enough to search a bit for similar projects. The deal breaker on this for me is the 1.14-inch screen. Middle age has made it much less pleasant to look at things that small.
Goodness, my watch has a bigger screen (my watch has a higher resolution, too). But I’m about to be eligible for a lot of senior discounts this year, so perhaps it isn’t built for the likes of you and me.
