Text: It is made of brass and is around the size of a large pocket watch, with a normal clock dial showing roman numerals and a smaller dial at the bottom for the second hand. The clock is suspended inside a swivelling brass ring fitted to the inside of a wooden box – this is the key to keeping the chronometer level even in an unsteady ship. –A History of the World in 100 Objects, Neil MacGregor Write two to three sentences explaining how the image reinforces the text.

The text uses descriptive details to help the reader understand how a chronometer works, and the image reinforces those details. The image allows readers to see all of the individual parts of the chronometer, such as the dials and the wooden case. It might be difficult for the reader to visualize how the chronometer is suspended in a swiveling brass ring, but the image helps the reader understand exactly how the chronometer is put together.
