De Bethune 2014

De Bethune: DB29 Maxichrono Tourbillon

The five central hands on this chronograph watch serve to make elapsed times easier to read than on a conventional chronograph display. An important element of the watch's identity, they follow the curves of the dial. They are each crafted from blued steel, except for the chronograph minute hand which is in rose gold. Seconds and minutes are measured on a scale with 60 graduations, hours on a scale of 24. All five hands are mounted on co-axial stacked wheels, a complex system requiring immense technical expertise.
