··Omega Qualified WatchmakerI personally have a threshold of damage I can live with and actually see as character- case and bracelet scuffing, lume color shift....and that’s about it. Beyond that to me it’s just abuse or neglect. Sure I can call those things patina, but they are damage and decay.
I think the same is true for everyone, but the point of that transition, as I've said is different.
I tend to think of patina as natural aging of something, so the change in colour of luminous material is the obvious example when talking of watches. Or the natural fading of a bezel.
Where some people can't stand this, others take an approach more like the Japanese concept of "wabi-sabi" in that things are often imperfect and perfection is somewhat transient.
