SIHH 2013: Roger Dubuis - a true chronometric marvel [Live Pics!]
Manufacture Roger Dubuis today lifted the veil on a truly remarkable new watch called the Roger Dubuis Excalibur Quatuor :
In short, the watch concentrates on the key tasks of a watch, that is
to keep time as precise and as consistent as possible.
To this end, the Manufacture Roger Dubuis invested 7 years of research. The outcome is a pièce de résistance featuring:
- 4 complete escapements
- 16 Hz overall frequency
- 5 differentials to coordinate the escapements, barrels and power reserve
- A simple but precise power reserve indicator
- 590 movements parts individually finished according to the requirements of the Poinçon de Genève
The overall goal was to balance the influences of gravity on the movement in real time. The four carefully positioned sprung balances work in pairs to compensate immediately for the rate variations caused by the changes in position. What the tourbillon achieves over the course of a minute, the Excalibur Quatuor achieves instantly.
Complementing its chronometric performance Quatuor also employs a sophisticated power reserve indication which displays the remaining autonomy with very few mechanical parts needed. The price to pay is actually that both power reserve hand and dial move in the same direction (something we have seen on Nomos watches, for example) giving a interesting twist to the display.
I will go through this with the help of the teasers I posted during entire January. For now here are the technical details.
Best,
Magnus
