Only one arcsec is a lot of resolution, you will not be able to avoid up-gearing if you want to achieve this.. And the accuracy will always be questionable..
My scope (with friction wheels ratio 1:20 or close to that) has around 7000 ticks per rot on both axes, which is around 180" or 3arcmin, enough for visual.
