"L'influence de la forme des bouts de pivots sur l'isochronisme du couple balancier-spiral" by E. Borer - Original magazine article (magazine clipping) which was removed from a 1953 Swiss magazine.
Text in the article is in French.
The opening sentence of the article reads:
"Par isochronisme, on etend l'independance du temps necessaire pour accomplir une oscilation de l'amplitude du balancier spiral."
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 3 pages in length (on 2 sheets of paper). At the end of the last page, in small text at the bottom of the page it reads, "Communication de la Manufacture des Montres Rolex, Bienne."
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.
