Can’t generalize like that.
GS finishing is like Swiss finishing of old. They stand alone today in that regard.
That being said, Rolex/Tudor always made the most robust cases/movements.

I can generalize because I am a certified master watchmaker.
"Grand" Seiko's are like Timex's to me. Now give me a Patek Perpetual Calendar or a Parmigiani Fleurier and we can talk quality.
Grand Seiko is not like timex, they’re on an entire different level, and as a watchmaker, I’m sure you know that.
I respect we have different interests in this space, and that’s OK, but GS makes has the best dial game in the world IMO, and I love them… I won’t respect them less because they’re Japanese. Instead I admire their OCD levels of perfection.
but I do have a Patek 5159 perpetual calendar… and admire high horology too.
