White enamel dial with a subsiduary seconds dial and blued steel hands, signed 'Parkinson & Frodsham London 948' and the broad arrow mark.

This deck watch accompanied Capt. William Parry aboard ‘Hecla’ in his attempt to reach the North Pole in June 1827. Parry used ‘sledge boats’ on the ice, but they proved too heavy to push, achieving a maximum 7 miles a day. As the ice was moving south at a greater rate, he was forced to abandon his attempt at 82° 45' latitude, the furthest reached until 1876.
