A Georgian or early Victorian wooden pocket sundial compass, also known as a 'Pantochronometer' or 'Magnetic Dial', dating from c.1840. The term pantochronometer was apparently coined in the early 19th century by Charles Essex & Co. of Clerkenwell, London. This particular type of floating sundial compass was patented by the London instrument maker Samuel Porter in 1824, who referred to these instruments as 'Magnetic Dials' and often labelled them to that effect on the base. Similar instruments are known to have been made in Europe in the late 18th century. Further details of the history of pocket sundials can be found at the excellent compassmuseum.com website.
This example features a turned wooden case and floating sundial compass card, incorporating a brass gnomon under a domed glass. The compass is in full working order and finds North very well.
