Blancpain Villeret Twelve Days Power Tourbillon Watch Review

The Blancpain Villeret Twelve Days Power Tourbillon Watch stands as a remarkable accomplishment within haute horlogerie, blending traditional craftsmanship with advanced engineering. Introduced in 2015, it became Blancpain’s first tourbillon powered by a single barrel capable of delivering a remarkable 12-day power reserve. This technical breakthrough showcases the brand’s pursuit of long-lasting precision and sophisticated innovation.
Classic Villeret Design – Blancpain Villeret Twelve Days Power Tourbillon
A defining highlight of the Villeret line is its commitment to timeless elegance. This model presents a pristine white grand feu enamel dial, adorned with slender Roman numerals that evoke a pure, classical aesthetic. The refined layout reflects Blancpain’s dedication to traditional Swiss watchmaking.

Located at 12 o’clock, the one-minute flying tourbillon makes a full rotation every 60 seconds. The mechanism incorporates a silicon balance spring and silicon pallet fork, improving performance through reduced friction, increased durability, and enhanced anti-magnetic resistance. These innovations significantly contribute to the watch’s impressive accuracy and stability.
Calibre 242 – Blancpain Villeret Twelve Days Power Tourbillon Movement

Turning the watch over reveals the meticulously finished Calibre 242. This self-winding movement features hand-engraved bridges, visible wheels, and a beautifully arranged architecture. The power-reserve indicator at 3 o’clock offers a convenient visual on remaining energy, while the barrel-charging gear at 6 o’clock showcases the mechanism’s internal complexity.
While Blancpain officially rates the running time at 12 days (288 hours), many owners have reported performance reaching up to 14 days — placing this model among the longest-running single-barrel tourbillon watches on the market. The movement’s exceptional energy efficiency reflects Blancpain’s technical mastery.
Case, Material Finishing & Wearing Experience
The piece features a 42 mm case crafted in rose gold or platinum. Blancpain’s signature double-stepped bezel enhances its classical look, while the well-proportioned 11.65 mm thickness offers comfortable wear for both daily and formal occasions. A sapphire case back allows a full view of the tourbillon and movement finishing.
The watch is paired with a hand-stitched alligator leather strap and a matching solid-gold buckle, completing its luxurious yet understated presence. For collectors who appreciate refinement, mechanical excellence, and long power reserves, this model stands out as a masterpiece.
