Which tool for micro adjusting

[Masteryacht]

Which spring bar tool do you guys use for micro adjustment on an oyster easylink clasp (blnr)? I bought a Bergeon 6767, but evidently got the incorrect size because the forked end is too wide to gain access to the bar. Also, im guessing it's not possible to use the caliper/tweezer ype tool because the bracelet would interfere with it's use? Is that correct?
Many thanks!
