A late 18th century or early 19th century, Compass Dial, signed on the chapter ring James Hall, with hand coloured paper compass rose. This pocket dial, first introduced in the mid 18th century, was used not only for telling the time during daylight hours, but was also the only reference against which many Georgian gentlemen could set their mechanical pocket watches.  The silvered chapter ring is engraved in Roman Numerals, and supports an engraved bridge holding the sprung gnomon. It can be rotated in the compass bowl, so that the dial can be set to the compass. The gnomon is hinged to fold for transportation and the screw on brass lid completes the instrument. The paper compass dial is printed with the cardinal points (32 compass points), four quarters of 0 – 90 degrees, as well a fine scroll centre rose and the iron compass needle has a counterbalance weight near the point. The dial is 2 1/4 inches diameter, has some detail turning on the lid and underside of the bowl and in good condition overall. -£545
