The patent Pantochronometer is a pocket Sundial/Compass that can be used to tell the time all over the world, C 1895. The base has the instuctions on it which are just about readable, see pic 4. Case looks to be sycamore and has a lovely patina, with no splits. The compass works well on a level surface. The face/dial is still clear and does not appear to be faded. The thin glass dome is in tact. Diameter 5,5 cm
