How the heck do I set the hour hand on 116710ln

[glenn_herwig]

So this past week I recently adopted a gmt master II. I have no idea how to set the hour hand. Where do I place it between the indices when the minute hand is already 20,30, 40 minutes into the hour? I'm familiar of all the positions and what nots. I've watched lots of videos it's just the hour hand part I'm having trouble with.

All the best,

Glenn
