Yes the part you have circled is the regulator arm and if the watch is running slow you need to move it toward the + this will move the regulating pin and in effect shorten the hairspring making the watch run faster. You should be very careful and gentle when doing this, I would be tempted to move it directly to the centre position because it has already be adjusted to run slower.

Has your watch been running accurately up to now ? it may be time to service the movement.

A watch timing machine greatly assists any adjustment of this type.
