You will easily navigate your airship when you have your wrist Navitron handy! This Victorian device is the equivalent of a modern GPS. Made of antique brass, this multi-functional device acts as sundial, latitude finder and compass, with locking button. All of the features, including sundial and angular latitude arm, fold flat for a compact look. The Navitron has been affixed to a heavy-duty brown leather band, making it accessible at any time.
