A Short History of the Buren Watch Company:

The Buren Watch Company was named after the location of its initial start up in a little village in Switzerland called Buren, located on the banks of the Aare. The firm started in 1842 making watch parts. In 1873 they started making complete watches and F. Suter officially founded Buren and initially called the company F. Suter & Co.

Buren sold many watches and movements with other company’s names on them such as Elgin, and were often used in Railroad Watches because of their accuracy and reliability.

The first ever micro-rotor automatic watch movement was patented by Uhrenfabrik Büren A.G. in the mid 1950s. When their "planetary rotor" automatic movement was released in 1957 in the "Super Slender" line, it was one of the flattest automatics of its time and derivatives of the movement competed with the Universal Geneva micro-rotor for thinnest automatic in the world for many years.

In the early 1960s Buren was sold in 60 countries. They created many brands for the various markets: Van Buren (South Africa), Steelco and Haste (Mexico) and Dugena and Monza which were sold in the United States.

Although Hamilton produced Thin-O-Matics wristwatch models with high-grade ETA movements as well, they were so fond of the Buren movement that in 1966 they purchased the company.

Hamilton (which became Hamilton International S.A. in 1968) kept producing fully assembled watches under the Buren name (alongside Huguenin (whom they purchased in 1959) and Vantage (purchased in 1962)). They kept Hans Kocher (Buren's chief designer) on as the president of Buren Watch Company S.A. which they owned and operated until Hamilton was in turn purchased by SIHH (later called SMH, now the Swatch Group) in 1971 (a controlling interest was purchased at that point, all watchmaking assets were then completely turned over in 1974). Buren went into liquidation within months and their impressive and productive 101 year existence came to an end in 1974.
