Text in the article is in English.
This article is Part I of a series. (Other articles in the series are not included.)
The opening sentence of the article reads:
"Timing machines, which enable the instantaneous rate of a watch to be determined, are coming into increasing use in repair work."
This article is Part I of a series of articles. (Later parts to the article would have been included in different issues of the publication and are NOT included.)
Headlines of sections in this article include:

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 10 pages in length (on 5 sheets of paper) and includes a number of small black and white diagrams 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. There is one small smudge mark in the margin on one page.
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.
[Please note: this is a magazine article/magazine clipping only; no watch, clock, parts or tools are included.]
Please note that this article is part of a series of articles. Other articles in the series are NOT included.
