First, there is nothing wrong with a proper re-lume.
However, a sloppy job can destroy your satisfaction and render a gorgeous example horrendous.
You do have to take what comes with a re-lume.
. It is not as valuable as an original lume dial, if that is important to you.
. It may cost more than a proper service dial, which will have working lume.
. A rare/collectible dial with a relume can drop it's worth by thousands, therefore the watch value drops as well.
Lastly, a damaged dial with missing or broken lume that is difficult to find can be enhanced with new lume. A trashed dial isn't valuable to anybody.
