The sextant has a green/black lacquered brass frame and a detached wooden handle. It has two index glasses, one above the other, which is adjusted by screws. It also has two horizon glasses, one above the other, which is adjusted by a square-headed screw and a detached key. The sextant has no shades. The glasses are linked to the station pointer arms by rods that each has a clamping screw on top and a tangent screw at the bottom. The two horizon glasses have a reflecting portion only.

Attached to the sextant is a threaded telescope bracket which is non-adjustable. The sight-tube is 78 mm in length and has a threaded pinhole eyepiece, three adjusting pins, and an adjusting key.

The instrument has a steel scale from 143° to 0° to 143° by 30 arcminutes, measuring to 130° on either side. The sextant has two steel verniers measuring to 1 arcminute, with zeros at the right and the left.

The sextant is contained in a rectangular fitted mahogany box with a brass carrying handle.

This instrument allows the two angles that are measured to be immediately protracted on paper, without reading it off first. Konstantin Edler von Pott of the Imperial Austrian-Hungarian Navy probably designed this sextant around 1870.
