Portable Sundial with Compass, Antique Finish, 9cm

Although not intended for accurate timekeeping, our portable sundial is a complete, functional replica of an 18th-century design in which the gnomon, which casts the shadow, can be set for latitude on a sliding scale; and the whole instrument oriented in the meridian by means of a magnetic compass in the base. A spirit level and height-adjustable legs ensure that the instrument is used upright. This enabled the instrument to become a completely portable time-keeping device in an age before the pocket watch. Antique-effect case measures 9cm diameter.
