I love mine on my dial, and yes, it’s an automatic.
The indicator “speaks” to me. When full, it tells me all is running well. When nearly empty after a couple days out of rotation, it tells me to wind the butter smooth movement to keep the time, date and GMT hand correctly set.
And I just like having the the extra blue hand on the dial.
Maybe “useless” to some, but far from useless to me. Aren’t all mechanical watches pretty much “useless” these days?
