Citizen BM7080-03E in every way, but with a good automatic movement in it. I do love mine, but it's going to be a headache replacing that solar rechargeable battery in it when it does finally give up the ghost.
I'll first answer the OP question: My favorite watch is any Citizen EcoDrive that has the Atomic feature (auto time setting from the Denver signal).
I inherited a Rolex from my older brother, but I truly do not like that it has to be moved all the time to keep it running. All the Citizen EcoDrive needs is to lay it down in a place where any light reaches it.
To your point, my older Citizen is almost 15 years old and is of course an EcoDrive Atomic.
A few months ago, I thought the crystal was getting a little scratched so I sent it in to the authorized Citizen repair center for a replacement.
As long as I was sending it in anyway, and the fact that it was 15 years old, I also asked them to replace the rechargeable battery.
The sent it back looking great with the new crystal, but the note they sent back said that they did not replace the battery because it checked out to be perfectly fine.
So I wouldn't worry about that battery. Just use the watch until it just quits running at which time it may end up being worn on your grandson's wrist as he attends your funeral.
