>Does Seiko's case hardening compare to Sinn and Damasko?
In a way.
They're all types of surface treatment, but Sinn and Damasko take it way further.
The downside to Sinn and Damasko's methods is there's only one type of optical finish possible: matte blasted.

> I think you are talking about grand Seiko rather than regular Seiko. Is that the case?
No. Grand Seikos do not have Seiko's surface hardening because it makes top-tier refinishing all but impossible.

>are you suggesting that new Seiko quartz movements are not up to par anymore?
That really depends.
The tech in modern Seiko quartzes is often superior (solar, etc.), but the build quality is often simplified.

Pic related for instance is the chronograph equivalent of this Tuna movement: >>14053313

Every subdial has its own little motor.

Seiko re-released a few Giugiaro watches that used to have this movement, but with a much cheaper movement with just one motor.

They still make this one though: >>14053313

Also, the Grand Seiko quartz (9F) has absolutely incredible tech, and is a (relatively) recent design.

Just to whet your appetite: every second the seconds hand makes two little jumps that look like a single jump to the naked eye, resulting in the greatest seconds hand stability possible.
