Octagonal in shape, it is finely engraved silver. The turntable is engraved with four hourly scales for latitudes: 43°, 46°, 49° and 52°.

Michael Butterfield (1635-1724) is a watchmaker of English origin who settled in Paris around 1663. Louis XIV's engineer for mathematical instruments, he invented different types of instrument including this sundial with compass which is designated as "Butterfield dial".
This copy is particularly interesting because it is very early, the punch makes it possible to date it from the period 1684 - 1687. He is one of Michael Butterfield's first productions and escaped the infamous fonts of Louis XIV of 1689.
The dial carries a punch on the back of the turntable, near the compass tank:
