The motion within is the caliber RD105SQ. It’s given the Geneva Seal (see more about Roger Dubuis Sports Activity Watch K10 Replica and the Geneva Seal here), which means you may expect a very high level of timekeeping and completing. For example, the skeletonized bridges have been NAC coated so they look dark grey, and they’re finished with circular-graining. The grade RD105SQ is made up 366 components. It beats at 3Hz, and owners may expect a power reserve of about 52 hours, which can be very decent considering it’s just one mainspring driving two fast-spinning tourbillons.Watches such as these are often divisive, but the colour scheme of this particular Roger Dubuis Excalibur Spider Dual Flying Tourbillon is rather attractive to me. I am not sure why, but when I look at it, I am immediately reminded of a glowing orange Lamborghini Aventador. This specific version of the Roger Dubuis Excalibur Spider Dual Flying Tourbillon watch is restricted to only 28 bits and the cost is $267,000. That is not enough for an Aventador, but you may be able to get a Huracán if you go easy on the options.Roger Dubuis has been on a spree of substance innovation lately. A few weeks ago, I looked at the Excalibur Carbon Spider Watch which had the very first movement to feature substantial use of carbon – specifically, the movement plate, bridges, along with tourbillon upper cage had been done in carbon. We also got to go hands-on with this view, the Roger Dubuis Excalibur Quatuor Cobalt MicroMelt which is the very first watch in the world to incorporate a situation constructed entirely from something called cobalt chrome — a high-strength alloy that serves as a acceptable background for the watch’s impressive quad layout balance.Roger Dubuis introduced the first Excalibur Quatuor model back in 2013, and they were already experimenting with materials on the watch, offering a acoustic version in a limited edition of 3 watches every priced at a staggering $1,000,000. Though, it is also a limited edition, coming in just 8 pieces. What was visually impressive then remains as such – take a look at the movie above of the four balances in action.
Roger Dubuis’s Excalibur Skeleton Tourbillon was presented for the first time in a 42 mm case at SIHH 2013. Retaining the same movement and styling, the watch is nonetheless radically different from its bigger brother.
In recent years Roger Dubuis watches were generally large and shiny. The ostentatious styling tended to overshadow the finer horological merits of the timepieces. Roger Dubuis is now reversing course. Earlier this year it unveiled the Excalibur 42 Skeleton Flying Tourbillon, a slimmer and smaller version of its signature timepiece. Now in a 42 mm case – it was previously 45 mm – the watch is decidedly more graceful and refined. Less intrusive than its heavier and bigger sibling, the Excalibur 42 tourbillon sits much better on the wrist and fits easily under a sleeve. The movement, however, is the same RD505SQ movement found in the larger model. All the bridges have been reduced to the bare minimum and shaped to resemble a pair of stars.
Because of the dark ruthenium coating on the bridges, the finishing is not easily visible. All the bridges are finished with perlage, or circular graining. The perlage is done to a high standard – the circles are closely and evenly spaced.
The rest of the movement is well finished, to Geneva Seal standards, though in terms of design and construction it is not particularly elaborate. Take the keyless works for instance, brushed and well bevelled but simple in form.
The Roger Dubuis Excalibur 42 Skeleton Flying Tourbillon is available in rose gold, priced at S$200,000 (~US$157,000) in Singapore, and in white gold, for S$215,000 (~US$169,000). Both prices include 7% tax. – SJX
