да нет, Sallaz-polisher - это станок такой, немецкий
вручную так никогда не сделать, имхо
плоскую поверхность можно отполировать "в зеркало" вручную (притирка на плоскости с помощью полировочной пасты), а не плоскую - вряд-ли
This is how and why Grand Seiko cases have mirror-like reflection and there are probably only a few other manufacturers in Switzerland who do cases at this level. Grand Seiko cases are polished by special machine – Sallaz polisher (originally imported from Germany in late 50s, polishing company called Sallaz) – the surface of the case becomes truly like mirror.
