1941 Grönograaf
Tantalum
Limited edition of 25 pieces

While Grönefeld produced a number of different watches endowed with a variety of complications, it had never made a chronograph… until now.

The 1941 Grönograaf is the latest creation to be conceived in Oldenzaal. It is a classical chronograph, but consistent with the Grönefeld ethos, it incorporates several ingenious details.

The ‘Premiere Edition’ will be encased in the rare metal tantalum and limited to just 25 pieces. Thereafter, Grönefeld will release 188 pieces in stainless steel.

This 1941 Grönograaf is the distillation of three generations of watchmaking know-how, of the professional journeys of both Horological Brothers and the manifestation of their extraordinary passion for horology.

A PURIST'S MOVEMENT

Unlike mass-produced cam-actuated chronographs, the 1941 Grönograaf features a classical configuration, namely a column-wheel and lateral coupling, a combination synonymous with high-end watchmaking. The calibre G-04 is a symphony of 408 parts and a wonderful exemplar of no-compromise watchmaking.

Mindful that chronograph movements are often subject to harsh forces that can sometimes scar hammers and bend hands, The Horological Brothers conceived a less aggressive system, a ‘soft reset’ mechanism. A centrifugal governor, positioned at 4 o’clock, typically seen on minute repeaters, slows down the reset function, thereby proving kinder to components while delivering a fascinating spectacle in the process. The governor includes two solid gold weights.

Depending on the position of the heart-shaped cams for the counter hands, the relevant minutes and seconds hands rotate clockwise or counter clockwise, heightening the sense of mechanical theatre. The 30-minute counter, located at 6 o’clock, features an ‘instantaneous jumping minutes’.
