Before battery-powered watches, some travelers carried a pocket sundial. This little wooden one folds shut, has a built-in compass, and includes time scales for different latitudes. The Smithsonian dates it to around 1795. *Pocket-sized timekeeping, powered by a shadow.* https://americanhistory.si.edu/collections/object/nmah_690195
