The outer side of the hinged outer LID is engraved with a coat-of-arms: the shield charged with a band between two flowers, on the crest a full face helmet and two wings similarly charged; it is closed by two small catches on the sides. Engraved lines are filled with coloured wax, usually red but occasionally in other colors. The inner face of this lid is engraved in red with a wind rose, with the names of the cardinal directions engraved in Latin on the sides (the 'N' in 'SEPTENTRIO' reversed); the names of the 16 directions engraved in German in the wind rose itself; and the numbers 1 to 16, starting from the East, engraved in the spaces in between. A SILVER PLATE, hinged opposite the outer lid and forming a sort of inner lid, contains a universal EQUINOCTIAL DIAL, engraved with an inscription in red and an hour scale divided to the half hours, numbered 1 to 12 twice, in black, on one side. A crosspiece held a now missing pin gnomon. The other side of the silver plate is similarly engraved but damaged on the top right corner. Reaching from the silver plate to the box below (when open) is a CURVED BAND for adjusting the latitude, engraved on the limb with an equal scale from  to 90, divided to ten, subdivided to two degrees, numbered by ten from 10 to 90. The other side is engraved in red, with a scale of latitudes divided to ten, subdivided to two with dots, but not numbered. In the upper centre of the box, below the hinged lids, is a BRASS PLATE engraved with a wind rose with 32 directions, with the pointers coloured in red, blue and green and the main winds in red. The corners contain engraved inscriptions, and a circular aperture in the centre originally revealed the compass beneath. The compass, now detached, is marked for magnetic deviation and engraved with the cardinal directions. On the other side of the box ????? is a sliding, gilt BRASS PLATE, on whose inner side is a NOCUURNAL, its alidade now broken. The nocturnal's silver revolving plate is engraved with the names of the cardinal directions; the intermediate directions are indicated by letters interspersed with star symbols. The hour scale is divided to the half-hour, numbered from 4 to 12 to 8. The index rotates on a zodiac scale, divided to ten degrees, subdivided to five, numbered by ten from ten to 30. The zodiac symbols are engraved on an inner circle. A handle for the nocturnal is fixed at the bottom of the plate and the spandrels have a simple foliate decoration. On the outer side of the brass plate is a pierced LUNAR VOLVELLE with aspectarium, engraved with the hours 1 to 12 twice, surrounded by a scale of hours, divided to the half-hours, numbered 1 to 12 twice, in turn surrounded by a ring of lunar days 1 to 29; with a simple foliate decoration in the spandrels. Below the brass plate is a REMOVABLE SILVER PLATE, its borders decorated with a simple line, inscribed with the maker's signature and the place and date of production. All four sides of the main box are engraved with blowing cherubs.
