Text in the article is in English.

Please note that this is "Part 1" of a series of articles. Other articles in the series are not included.

The opening sentence of the article is:

"In this important article, the author describes an investigation into the precision clocks, by Jost Burgi in particular, used for astronomical measurements before the pendulum clock was invented."

The magazine article was carefully removed from a Swiss magazine.

[Please note: this is a magazine article/magazine clipping only; no watch, clock, parts or tools are included.]

The article is 8 pages in length (on 4 sheets of paper) and includes a number of small black and white images within the text.

As with most vintage magazine clippings, there is some yellowing to the paper due to age as well as light wear and small bends.

The magazine article was carefully removed directly from a Swiss magazine. It is not a copy or reproduction. The rest of the magazine is not included.
