DB29 Maxichrono Tourbillon

The founders research of follows on from that undertaken by the great horologists of the age of enlightenment, while assimilating the new technologies and materials to which the fundamental calculations and principles of conventional mechanics have been applied. The various innovations emanating from the De Bethune laboratory not only bear witness to these intentions, they also express the conviction that there is much unexplored territory in the field of watchmaking technology. Work on the regulating organ that is at the heart of every watch obeys well-known physical properties: inertia, mass, elasticity, surface friction and magnetism. Fundamental to the improved precision and efficiency of watch movements are such technological advances as the patented balance-spring with flat terminal curve, balance-wheels in silicon and white gold or in titanium and platinum featuring maximum inertia for a minimum weight, as well as the development of a real tourbillon for the wrist in silicon and titanium. The DB29 Maxichrono Tourbillon, the result of seven years of research and development, is the only one of its kind. This exceptional patented chronograph, packed with innovations, embodies the essence of De Bethune's watchmaking. De Bethune marks a significant technological breakthrough in the history of chronographs, the result of continuous research heralded by the DB21 Maxichrono in 2006. Constant innovation relying on an extensive knowledge of age-old expertise has enabled the brand to simplify and enhance the reliability of the absolute clutch system so that it can be implemented in a movement manufactured by the production workshops in the Swiss village of L'Auberson.
