Good To Know:
- Chronograph with visible slow return to zero regulator
- Number 25 of a limited edition of 25 in tantalum
- Winner of 2022 Best Chronograph prize at GPHG 2022
The Grönefeld brothers, Bart and Tim, have been redefining independent watchmaking since 2008, earning a reputation for their mastery of complications and 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.
With the launch of their first chronograph model, aptly named the Grönograaf—a play on words between their name and the Dutch spelling of “chronograph”—the brothers were again honored at the GPHG, receiving the Best Chronograph Wristwatch award in 2022.
The timepiece is as technically ingenious as it is visually captivating. The dial layout is both unconventional and striking, featuring a time subdial 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, forming 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 creating a mesmerizing visual display.
The Grönograaf was first introduced as a limited edition of 25 pieces in tantalum—like the present example—which quickly sold out, followed by a limited edition of 188 pieces in steel. Bearing the number 25/25, the present example represents the final tantalum model ever produced.
