Offered in this auction by Second Vintage This is an exceptional example of horological innovation and mid-century elegance, featuring Buren’s legendary micro-rotor technology.

Its combination of a technically fascinating movement and a pristine, classic aesthetic makes this a standout offering for the discerning enthusiast. Brand: Buren Model: Grand Prix Super Slender Reference Number: 77013 Movement: Automatic Micro-Rotor Dial: Silver Sunburst Case Size: 35 mm (excluding the crown) Case Material: Stainless Steel Production Year: c. 1960s Condition: Excellent vintage condition with a remarkably preserved dial and very strong mechanical performance. (timegrapher test included below) Dial and Hands The watch presents a stunning silver dial finished with a fine sunburst texture that plays beautifully with the light. It features applied silver baton hour markers that remain crisp and bright, matching the sharp Dauphine-style hands. The text is printed in sharp black typography, proudly displaying "Buren Grand Prix" at the top and "Super Slender Automatic" at the bottom. The dial surface is exceptionally clean, showing virtually no signs of aging or patina, preserving a near-factory fresh appearance that is rare for a watch of this vintage. Case and Crystal The 35mm case is crafted from stainless steel and features distinctively shaped, angular lugs that add architectural character to the profile. The case shows honest, light wear consistent with careful usage, with lines that remain defined. The caseback is fully detailed with the reference number 77013 and branding, showing some surface scratches from past opening attempts but retaining deep, legible engravings. The acrylic crystal is clear and free of distracting marks, ensuring an unobstructed view of the dial. Movement Powering this timepiece is a high-grade Buren automatic movement featuring the celebrated micro-rotor design. This technical innovation allows the rotor to sit flush within the movement plate rather than on top, enabling the "Super Slender" profile. The 25-jewel movement is visually impressive with clean bridges and a gold-tone finish. It is performing exceptionally well; timegrapher results indicate an accuracy of +6 to +8 seconds per day with strong amplitude, which indicates a healthy movement offering reliable vintage performance. Strap The watch is fitted with a black leather strap featuring a unique geometric scale texture and white contrast stitching. The strap is in excellent condition and complements the vintage character of the watch perfectly, securing with a steel pin buckle. Condition This timepiece is in excellent vintage condition. The most notable attribute is the superb preservation of the dial, which is free from the spotting often found on silver dials of this era. The case retains its original geometry without signs of over-polishing. The movement is clean, correct, and running strong. Dimensions The case measures 35 mm in diameter excluding the crown, a classic dress watch size that wears elegantly on the wrist due to the slim profile and elongated lugs. Remarks The Buren Super Slender is more than just a dress watch; it is a piece of engineering history. The micro-rotor movement found inside is a direct ancestor to the technology later used in the famous Calibre 11 Chronomatic. Finding one with such a pristine dial and in such strong running condition is a distinct opportunity for the collector. History Buren was a highly respected Swiss manufacturer known for being a true "Manufacture" that produced its own calibers. They were key innovators in the field of automatic movements, specifically competing to create the thinnest automatic watches in the world during the 1950s and 60s. Their patent for the planetary micro-rotor placed them ahead of many competitors and cemented their legacy in watchmaking history before the brand was eventually integrated into the Heuer-Leonidas and Hamilton groups. / Second Vintage SKU: BUR5RLDGF0000
