Because during WWII the U-Boats actually went into battles

exactly like on this virtual replica of the compass.
3 rings, 1 fixed, 2 rotatable - 4 rings of numbers:
- outer ring, relative bearing, ring is fixed (to the boats heading)
- middle ring,. true bearing, ring rotates and shows true north, it also has a second ring of mirrored numbers on it (flipped by 180°)
- inner ring, true bearing, rotates, 1/36 scale for 0.1 degree precision
I guess any navigator would prefer a precision of 0.1 degree over just 1 degree.
Alrighty.
