Hi again, not for Seiko.
Steven @ Wah Foong a.k.a 'watchrepairkl' on IG, assisted me to change the whole movement on a Rado, a Raymond Weil and servicing on a couple of Rolexes.
He is a watchmaker that is hired to repair the parliament grandfather clock. So his competency is world class.
Too many clients. He's super busy. But very forthcoming.
