Watchmakers in the third generation, the Dutch Bart and Tim Grönefeld received specialized education and in 1990-s had worked on the Swiss manufactory Renaud et Papi, which produced calibers for a range of recognized luxury brands. After returning home, the brothers opened their business and began to create luxury dress models with unusual complications. Over the last few years their products have won two statues of the Grand Prix d’Horlogerie de Genève. In 2014, Parallax Tourbillon has won in the nomination “best tourbillon watch”, and two years later 1941 Remontoire became the winner in the category “best men’s watch”. Bart and Tim always work together and, by their own admission, almost never argue on creative issues, and are often inspired by almost forgotten chorological masterpieces of past centuries.
