====== Buren Calibre 82 ======
**Calibre 82** was a [[high beat]] [[automatic]] watch movement by [[Buren]].

Developed in the late 1960's, Calibre 82 was intended to compete with the high-beat movements coming from [[Zenith]], [[Girard Perregaux]], and others. But Buren was sold to [[Hamilton]] before development finished and just 250 movements were produced. It was tested in 1970, receiving one of the highest [[chronometer]] ratings ever recorded It achieved a Chronometer Index of 4.4, making it the most accurate mechanical movement ever certified! It achieved a variance of between +15 and +60 seconds per 30 days, far exceeding the test parameters.

The Calibre 82 movements were sold along with Buren in 1971 and remained unused until a run of 238 "Calibre 82" watches was produced in 1998 and 1999.
