The Grönefeld brothers, Bart and Tim, have been redefining independent watchmaking since 2008, earning a reputation for their mastery of complications and their dedication to technical innovation. Their creations, such as the Parallax Tourbillon and the 1941 Remontoire, have garnered international acclaim, including two prestigious awards at the Grand Prix d’Horlogerie de Genève: Best Tourbillon in 2014 and Best Men’s Watch in 2016. Despite their impressive portfolio, one complication had remained conspicuously absent from their repertoire—until now. With the introduction of the 1941 Grönograaf, the Horological Brothers have turned their attention to the chronograph, delivering a timepiece that is as technically ingenious as it is visually captivating.

At its core, the 1941 Grönograaf is a classically executed chronograph, featuring a traditional column-wheel and lateral clutch mechanism—a hallmark of haute horlogerie. However, the Grönefeld brothers have elevated this complication with a host of innovative features. The dial layout is both unconventional and striking, with a subdial for the time at 1 o’clock, a power reserve indicator at 10 o’clock, and a 30-minute chronograph counter at 6 o’clock. At 3 o’clock, a centrifugal governor—typically found in minute repeaters—takes center stage, serving as the heart of the watch’s groundbreaking "soft reset" mechanism. This ingenious system slows the reset function, reducing the harsh forces that can damage traditional chronograph movements, while also providing a mesmerizing visual display.

The present example numbered 5 of a limited edition of 188 pieces, is the first Grönograaf to appear at auction. Consigned by the original owner and accompanied by its full set of original accessories, this timepiece represents a rare opportunity to acquire a "waiting-list" watch that has already become a modern icon of independent horology.
