If you wear an automatic watch (self winding) and it is in good condition (well oiled and clean) then if you wear it every day, you will never have to wind it. It should maintain a 40 hour power reserve, so you can theoretically leave it on your nightstand for almost two days and it will still be running.
The largest variable here is how much you move around during the day. If you are a strictly desk-bound office type then you MAY not move around enough to keep that 40 hour power reserve fully charged.
Accuracy has almost nothing to do with the power reserve. If your watch is fast or slow, it can be adjusted for better accuracy but winding it every day will not help this. Let it go for a week, and see how fast or slow the watch is, then calibrate it.
