...of wristwear with time display.
They have mechanical escapement or quartz oscillator or electronic vibration "movements".
Some even have other functions than timekeeping like altimeter, compass, ocean tide, thermometer, barometer, heart rate, exercise, sleep and calorie counting.
The point is that eventually, we stopped using those extra functions.
So, owning a device does not equate to using the device! 😉
