Dude. Quit obsessing.
That is a good looking watch, and the movement is showing 0 beat error. That amplitude can be described as healthy, not too high. Without movement pics, I would say it looks like you probably have an ST 2130 in there which has a stainless mainspring, and tends to have a higher amplitude when running well because of this.
Find a good watchmaker and get it serviced, it will be dirty. Obsess about that, and it will run forever.
