@ ubi, nope, no screw down just winds in the closed position and pull out for time adjustment.
Though it's not supposed to have a hack function sometimes when I do pull the crown out the seconds stop running. Weird I know
Well a small update, it's been running pretty smooth for 3 - 4 hours now with constant wear and going in and out running errands. Hopefully the problem will solve itself or else I might have to take it apart and shorten the stem.
Thanks for all the help ubi
