Roger Dubuis is one of the high-end watch manufactures that participated at this year’s Watches&Wonders exhibition. The luxury watch exhibition, organized by the Fondation de la Haute Horlogerie, was a perfect opportunity to launch a number of new models, including the spectacular Roger Dubuis Excalibur Spider Pocket Time Instrument, which is an extremely large pocket watch equipped with four separate balance wheels, limited to 28 pieces worldwide and priced at $468,500.
The new Roger Dubuis Excalibur Spider Pocket Time Instrument is made of lightweight titanium, which allows it to spread across the 60 mm diameter, while measuring 20mm in thickness. The watch is mounted on a special titanium chain, and delivered with a desk stand, which turns it to a desktop clock. The large housing accommodates Roger Dubuis' RD101 movement, which has also been used for Roger Dubuis Excalibur Quatuor, with four balance wheels connected through a series of differential gears. The purpose of this highly complex innovation is to compensate for inaccuracies of individual balance wheels, thus improving the overall precision of a watch.
The fully skeletonized dial reveals a power reserve indicator at 6 o'clock position. Even though it features two arcs and a dual-sided hand, it provides information about a single power source. This unusual design is purely poetic and has no practical function at all. The movement is made of 590 individual parts, and no less than 113 jewels. The movement beats at a frequency of 4 x 4Hz, which is actually a standard frequency of 28,800 vibrations per hour, since the four balances' timekeeping is averaged.
In the spirit of Roger Dubuis tradition, the Excalibur Spider Pocket Time Instrument is stamped with the Poinçon de Genève, wich is visible at the 6 o'clock position. The watch is water resistant to 30 meters, nad it has a reference number RDDBEX0506. For more information, please visit rogerdubuis.com.
