The highlight of this watch is its rare Swiss automatic micro-rotor movement. As visible in the movement photos, the mechanism is beautifully constructed with 25 jewels and fine finishing. The micro-rotor system integrates the oscillating weight into the movement plate, reducing thickness and showcasing Buren’s technical innovation. The movement is signed “Buren Grand Prix Swiss Made,” confirming authenticity.

Story & Heritage:

Founded in Switzerland, Buren became one of the most technically forward-thinking manufacturers of the 20th century. In the 1950s and 1960s, the brand gained recognition for its micro-rotor automatic movements, which were revolutionary at the time and later contributed to the famous Chronomatic project alongside other major Swiss brands.

The “Super Slender” concept reflected Buren’s ambition to create elegant, thin automatic watches suitable for daily wear and formal occasions alike. The Grand Prix line represented quality, innovation, and prestige within the brand’s collection.

This example embodies that spirit — a compact 34 mm case paired with advanced mechanics and timeless design. It is a wonderful opportunity for collectors who appreciate historically important Swiss engineering and understated vintage elegance.

The watch will be carefully packed and shipped insured.
