DB2119 incorporates the major De Bethune technological breakthroughs:
Self-regulating twin barrel* – The barrels are specifically designed to eliminate friction and efficiently transmit a maximum of energy. (* Patents registered by the Manufacture De Bethune)
Silicon/white gold balance wheel* with flat terminal curve – Its exceptional lightness enables this balance wheel to reduce mechanical friction and deliver an ideal inertia/mass ratio. The principle of the flat end curve, placed on the same level as the balance-spring, compensates for off-centering and facilitates its fastening. (* Patents registered by the Manufacture De Bethune)
