A Grönograaf, the very first chronograph from brothers Bart and Tim Grönefeld. Advancing the chronograph complication with bespoke architecture, it features a landmark 'soft reset' system through use of a centrifugal governor. Its 408 components are exceptionally well-finished, a dramatic exhibition of steel bridge work. Made in just 188 examples, this steel Grönograaf is amongst the most technically refined chronographs ever created.
