Overview

Grönefeld is an independent Dutch watchmaking brand managed by brothers Bart and Tim Grönefeld, third-generation watchmakers whose family heritage dates to 1912. The brand produces limited quantities of high-complication timepieces, including tourbillons and minute repeaters, positioning it in the haute horlogerie segment with annual output of 50-70 watches.124

History

Johan Grönefeld established a watchmaking workshop in Oldenzaal, Netherlands, in 1912. His grandsons, Bart and Tim Grönefeld, relaunched the brand in 2008 with the GTM-06 Tourbillon Minute Repeater after initial designs in 2004. The brothers, trained in Switzerland, maintain family involvement in all production stages, focusing on independent high-end complications.1248
