I’m no expert but I do like seikos. Is it possible your seiko is magnetized?

It's running within specified limits for a caliber 6R54 (-15 / +25 spd).

May just need adjusting, may need a service. Until it can be assessed by a competent watchmaker who knows.

It remains my daily wear watch and I guess every now and then I’m showing up early. I adjust it about once a week.
Here she is with my new Shadow System Cr920x.

I have a few Seikos, 4R and 6R. Movement is all over the place with all of them. Look great and wear well but they aren’t my best timekeepers.
