Astronomy

Accession Number: 2012.ast.8

Description:

The chronometer is inside green felt lined cubic box. It has a heavy time piece suspended in the middle of a cubic wooden box, with top opening to view timepiece (through a glass pane) and middle opening with key to access timepiece. Inside, adjacent to the timepiece on the upper right corner is a brass winding key. On the lower right corner there is a knob to move a lever which allows the timepiece to rotate in both directions (such that if the chronometer moves the face of the timepiece always remains pointed upwards). Timepiece has a metallic clock face (I-XII) with minute and hour hands and a smaller face (0-60) with a second hand. There is also a dial marked from 0 to 56 (in increments of 8), labeled “Wind”.
