UPDATE for those interested in knowing what the strange division of the inside circle is....I have found out how it works

The inside circle is in fact a rotating wheel. It represents 10 degrees, and is there for a quicker visual estimate of course change and for increased precision in steering.

How it works:

The inside wheel will do a full turn each time the course is changed 10 degrees, and it can be used for very precise smaller course changes (Even a tenth of a degree). Consider it a sort of "magnification" of the main compass dial, or you can also think as example how your average analog wristwatch works: For each hour mark the small pointer displaces, the large pointer (minutes) does a full turn in the sphere. It works exactly the same but instead of 1 full turn=12 hours small needle/1 hour big needle, these compass dial wheels work as 1 full turn=360º compass rose/10º in the inner wheel.

Here is a video where you can see in minute 2.04 how the inner wheel does a full turn for a 10 degree course change in the main compass wheel:

And here is a link to the present day Anschütz company, which still manufactures gyro repeatesr using the same system of two wheels, large (360º) and small (10º):

Obviously the in-game graphics I provided will NOT work like that, nor can I think of a way of having them work so, therefore we are stuck with a fixed inner dial.

Happy hunting all
