Consider the following refactoring of your code
First, the locator pane is used to set a point location constrained on a circle with unit radius (this part borrowed heavily from an example in the documentation for LocatorPane). A degree value is then calculated from the coordinates of tha tpoint.
Secondly, the input field is used to read in a degree value, which is then used to update the position of the dynamic point pt using the second argument of Dynamic.
DynamicModule[
{pt = {0, 1.}},
Column[{
"Degrees:", Dynamic[(ArcTan @@ pt)/Degree],
LocatorPane[
Dynamic[pt],
Graphics[{
Circle[],
PointSize[Large],
Dynamic[Arrow[{{0, 0}, pt/Norm[pt]}]]
}],
Appearance -> None
],
InputField[
Dynamic[(ArcTan @@ pt)/Degree, (pt = N@{Cos[#1 Degree], Sin[#1 Degree]}) &],
FieldSize -> Tiny
]
}, Alignment -> Center
]
]
This keeps both fields in sync with each other:
