My new ZF Tudor Black Bay GMT with the A2836 movement is running slow. I've got a time grapher and have successfully regulated some of my other movements but this one seems a bit more stubborn.
My question is how far can you turn the eccentric regulator screw? I've gone to a point where the screw slot is perpendicular to a line between the screw and the spring pivot and I'm still about -15 sec/day. Can I effectively turn the screw further or am I on the wrong track here? Everything I've read regarding spring problems with too much oil causing sticking, etc result in a fast movement, not a slow one.
Thanks.
