Whereas all GS I've checked on their website is:
-3/+5 seconds per day in static position
-1/+8 seconds per day in "normal use" or even -1/+10 seconds per day
The best one I found in "normal use" is their tourbillon which is -1/+5 seconds per day (which is still worse than the Master Chronometer certification)

Also, Rolex and Omega/Tudor Master Chronometer are resistant to magnetic field, where GS aren't.

Again, I'm only comparing mechanical movements, not quartz or quartz-based movements.

FWIW, my Rolex Submariner 114060 is more accurate than my Omega Seamaster with the 8800 co-axial movement.

It’s not that the Omega isn’t accurate. It’s very accurate. It’s just that it’s not as accurate as my Submariner.

You’re drawing conclusions based on the specifications you see listed on the internet.

I’m basing it on first hand, real world experience. I wear both of these watches on a regular basis.

YMMV.
