De Bethune has won a prize for the best chronograph of the year at the Geneva Watchmaking Grand Prix for its DB29 Maxichrono Tourbillon.

The prize‐giving ceremony for the 14th edition of the Geneva Watchmaking Grand Prix (GPHG) was held at the Grand Théâtre in Geneva on October 31st 2014, in the presence of Swiss Federal Councillor Johann Schneider-Ammann, the authorities of the Canton of Geneva and representatives of the international watch industry. Among the pre-selected watches, the international and highly qualified jury of this 14th edition chose the DB29 Maxichrono Tourbillon to receive the prestigious award of the best chronograph of the year.



The patented chronograph was the result of seven years of research and development. It comes in a rose-gold case featuring De Bethune’s trademark cone-shaped lugs with a single push button at three o’clock that operates the chronograph.




The chronograph measures long elapsed times with counters for 24 hours, 60 minutes and 60 seconds. Precision is ensured by the De Bethune 30-second tourbillon in silicon and titanium, which weighs a total of 0.18g and is one of the fastest and lightest in the market.



The absolute clutch operates in a system engaging the two traditional clutch methods to allow the different chronograph counters to function semi-autonomously:

– The chronograph seconds are governed by the new absolute clutch system;

– The minutes counter is controlled by a shifting pinion;

– The hours counter is engaged by a horizontal clutch.



Three different types of clutch behind three semi-independent systems controlled by three column-wheels thus govern the different chronograph elapsed-time counters.

In this way 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.
