About GRØNE Oldenzaal

Our Story

Bart and Tim Grönefeld – the Horological Brothers – are proud to introduce GRØNE OLDENZAAL, a new line of mechanical timepieces aimed at making their unique creations more accessible to watch collectors.

"This is a significant project to us. The high demand and price points of our atelier-made Grönefeld watches mean that our watchmakers, our children, and our friends cannot easily access a Grönefeld watch. With GRØNE, this is changed. Now many many more can wear a watch we designed, and at a quality level that meets that of our atelier-made watches."

“Grönefeld watches often take months or years to manufacture. But with our small team of watchmakers, we can currently only make 70 to 80 watches per year. With Grönefeld, we have had long waitlists and so have had to turn away collectors. With GRØNE, we hope to bring our watches to a wider audience while maintaining high standards of design, aesthetics, and quality.”
