mid-century vintage ship's wheel weather instruments, barometer etc. Germany

Vintage mid-century weather station made in Germany. These have brass figural ships wheels bezels around the instrument faces. There is an open escapement aneroid (without mercury) barometer to measures the atmospheric pressure, a thermometer (calibrated in degrees F) and a hygrometer. The barometer is marked "West Germany" on the face and the hygrometer is marked "Germany"

This weather station measures about 15" high and 3 1/4" across the face of the barometer (5 3/4" over the brass ships wheel). The barometer and thermometer both work well. The hygrometer is reading 100% and we're pretty sure that that is incorrect and are not sure what is wrong with it. It may just need recalibrating or it may need repair.
