The name Grönefeld and the art of watchmaking have a family history spanning a hundred years, originating in the ancient town of Oldenzaal in the Netherlands. It is here, in a shop directly under the view of the ancient basilica church and its tower dating from 1240, that Johan Grönefeld began his career as a watchmaker in 1912.
This marked the beginning of a small and highly talented dynasty of Grönefeld watchmakers which now sees brothers Bart and Tim Grönefeld carry the baton. Their workshop is located in the same building as that used by their grandfather Johan, representing a continuous, unbroken watchmaking family history that is exceptionally rare to find anywhere in the world today.
In 2008, after working anonymously behind the scenes for prestigious Swiss brands, they presented the first watch bearing their own name, the GTM-06 Tourbillon Minute Repeater.
In 2010, Bart and Tim presented their second watch, the One Hertz, the world’s first series wristwatch with independent dead seconds and featuring a completely new movement, the G-02 Calibre.
In 2014 at the Baselworld, Bart and Tim again presented their new invention, the Parallax Tourbillon, which features a "flying" tourbillon with a large central seconds hand, stop seconds, a power reserve indicator and an innovative winding-setting mechanism. The completely new in-house movement, Calibre G-03, displays sophistication and craftsmanship at the very highest level. It also brings them the first award at GPHG, the Best Torubillon Watch Prize.
In 2016, they launhced another new model 1941 Remontoire with a new in-house movement, Calibre G-06. It equips with a sophisticated constant force system. It again brings them a GPHG award, the Best Men's Watch Prize.
