Bart and Tim Grönefeld were pleased to exhibit at the record-breaking 2026 edition of Watches and Wonders, held from 14 to 20 April in Geneva. A total of 60,000 visitors from across the globe attended this year’s showcase of horological novelties. At the Grönefeld booth, Bart and Tim, together with the fourth generation, presented the “7 Sins” project, created in collaboration with master engraver Kees Engelbarts. This exceptional set of seven unique watches has since found a new owner. Yet this remarkable project was not the only new creation from the Grönefeld brothers…

Some ideas refuse to be rushed… How it began: A meeting of two crafts. For nearly 30 years, Bart and Tim have shared a close friendship with Kees Engelbarts — a Dutch master engraver based in Geneva, renowned for his exceptional craftsmanship. Throughout these years, one idea remained: to combine his art of engraving with their horological creations. Grönefeld and Kees Engelbarts had collaborated before, but in 2022 they set out to make something extraordinary. Today, Bart and Tim present the result: A set of 7 timepieces, each representing one of the 7 Sins. A project defined by patience, mastery, and an uncompromising pursuit of excellence.
