DB21 Single-Button Maxichrono
The design of this watch is the natural consequence of technical choices. The unique and exclusive minute and hour hands (which are very complex and costly to produce) are manufactured entirely in-house. The five coaxial superposed hands are designed to attain perfect readability of the chronograph time in any instant. Inside Information: This watch uses the triple parachute system created by De Bethune to protect its exclusive balance-spring system, constituted of a balance bridge in titanium and a titanium-platinum balance wheel, with a double spring that fixes the two counter pivots of rubies.
