Period
late 18th to early 19th century
Western Europe, England, Georgian to early Victorian era, ca. late 18th to early 19th century CE. A turned wood pocket pantochronometer, also known as a floating-card sundial compass.
The circular case contains a paper dial printed with Roman numerals for hours and directional indicators, beneath a domed glass cover. A brass gnomon rises from the center, aligning with the compass card to cast a shadow for solar timekeeping. The floating magnetic card indicates orientation; the card is currently stuck in place. The removable lid fits over the top for travel protection.
