I have a fascination with the subject of smart watches - specifically, those I can hack on myself (i.e. no iWatch/Garmin/etc.) - so I have a collection of them .. a Watchy, an Oscilloscope Watch, the PineTime, numerous LilyGo ESP32 thingies, the M5Stick, and so on.
I don't ever wear them but I sure do love hacking on them, and they are the perfect platforms for exploring PlatformIO, FreeRTOS, ZephyrOS, and so on. I admit, its mostly just for hacking/exploration of embedded for that form factor, which is great. (I've also gotten paid jobs on the basis of that hacking, which is also great.)
Every now and then, though, I look at the pile of devices and think "I should probably track my biometrics, and try to work out how to get healthier with the watch as my primary bio- I/O tool", and I dig in .. its kind of fun to have a database of the last months heart rates ("see honey, I did enjoy our date last week"), step counts, and so on.
But I just can't comfortably work with a watch on my wrist, so I don't wear them.
For sure, I'm putting "make a custom watchface for the PineTime and Watchy" on my list of things to do next time I open that particular drawer of forgotten things ..
