A watch link running at 2.5 Hz that's been manually adjusted "in X positions" (to account for positional variance on the wrist) and isochronism can easily deliver link chronometer-level precision. A poorly regulated movement can be affected by all sorts of link bumps in the night – regardless of frequency – but if it's been effectively regulated by a watchmaker, then it will be better-suited for the motion of your wrist on a daily basis.
