"An Original and Interesting Form of Balance Spring Attachment" by Pierre Beguin - Original magazine article (magazine clipping) which was removed from a 1950 Swiss magazine. Text in the article is in English. Mentioned within the article is a device which was "invented and patented by M. F.-A. Robert-Charrue of Le Locle."

The opening sentence of the article reads:

"The problem of easing the adjusters task without impairing the accuracy of the watch has long been a thorny problem to watchmakers. Mechanical stability, temperature compensation, isochronal and positional adjustment have all called their attention. There appear to be countless sources of troublesome errors, and when one has been overcome another raises its head."

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 2 pages in length (on 2 sheets of paper) and includes a few small 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.

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.
