The Paradox of the Daily Hyper-Watch
In the world of luxury horology, the term 'Hyper Horology' is often synonymous with 'fragile.' We are taught to expect that any watch featuring extensive skeletonization and a micro-rotor should be kept in a safe, brought out only for the most sterile of black-tie events. Roger Dubuis, however, has spent the last decade dismantling that prejudice. With the Monobalancier RDDBEX0956, they haven't just created a movement that looks like a starship; they’ve built one that can survive a Tuesday at the office and a Saturday on a yacht.
At Vivir, we focus on the reality of the wrist. We care less about the marketing fluff and more about how the crown digs into the back of your hand when you're typing, or how the gold reacts to a humid afternoon in the city. The RDDBEX0956, cased in the brand's proprietary EON gold, is a fascinating study in high-contrast living. It is a watch that feels like a piece of heavy machinery, yet it is finished with the delicacy of a 19th-century pocket watch.
Case Architecture and Wearability
The first thing you notice when strapping on the RDDBEX0956 is the lugs. Roger Dubuis uses a triple-lug system that has become a visual shorthand for the brand. While this adds to the visual complexity, it serves a functional purpose: it distributes the weight of the 42mm case more evenly across the strap interface. The lug-to-lug measurement of 50.5mm sounds daunting on paper, especially for those of us with sub-17cm wrists. However, the lugs drop away sharply, following the natural curvature of the forearm.
The case material, EON Gold, is a 5N pink gold alloy that is specially formulated to be more resistant to salt water and tarnishing. In a week of wear, including a particularly humid day of travel, the gold maintained its deep, warm luster without the slight 'greying' that can sometimes affect standard rose gold. The notched bezel and crown guard give the watch an aggressive, serrated profile that feels wonderful to touch, though you'll find yourself cleaning dust out of the bezel notches with a soft brush more often than you'd like.
The RD720SQ: A Masterclass in Skeletonization
The heart of this watch is the RD720SQ caliber. Unlike many 'open-worked' watches that simply cut holes in an existing plate, this movement was designed from the ground up to be a skeleton. The signature Roger Dubuis star bridge is not just an aesthetic choice; it provides the structural rigidity needed to keep the gear train in perfect alignment. The star's tips point toward the hour markers, creating a sense of explosive energy radiating from the center of the dial.
One of the most impressive technical updates in this reference is the micro-rotor at 11 o'clock. Roger Dubuis has optimized the inertia of this rotor to reduce its sensitivity to shocks, a common weakness in micro-rotor designs. During my week of wear, the automatic winding was virtually silent and highly efficient; even after a sedentary day of writing, the power reserve remained topped up. The use of diamond-coated silicon for the escapement wheel and pallet stones is another nod to modern durability, reducing friction and the need for frequent lubrication.
Legibility and the Real-World Week
If there is a critique to be made of the RDDBEX0956, it is the classic skeleton watch struggle: legibility. The hands are satin-brushed and shot-blasted with Super-LumiNova X1 filling, but against the backdrop of the intricate movement, they can occasionally get lost in high-glare environments. However, the redesigned hour markers on the flange are sharp and clear, and after forty-eight hours, your brain 'trains' itself to look for the tips of the hands rather than the whole structure.
On Wednesday, I wore the watch through a series of transit transfers and a quick gym session (though I wouldn't recommend the latter for a $75,000 timepiece). The 100 meters of water resistance provided a level of psychological comfort that most skeleton watches simply don't offer. You don't have to panic if you get caught in a sudden downpour or if you accidentally submerge your wrist while washing your hands. This 'lifestyle proofing' is what separates Roger Dubuis from many of its boutique competitors.
Investment and the Vivir Verdict
Let’s talk numbers. At a retail price of $75,000, the RDDBEX0956 is a significant investment. It sits in a price bracket occupied by the heavyweights: the Patek Philippe Aquanaut, the Vacheron Constantin Overseas, and the Audemars Piguet Royal Oak. From a pure resale perspective, the Roger Dubuis does not hold its value as stubbornly as a steel Nautilus. You are likely to see a 30-40% drop on the secondary market the moment you walk out of the boutique.
However, the value proposition here isn't about financial arbitrage; it's about the level of hand-finishing. Every single component of the RD720SQ is finished to Poinçon de Genève standards—meaning every surface, even the ones you can't see, is polished, chamfered, or grained by hand. You are getting a level of artisanal craft that is often missing from the mass-produced 'hype' watches of its rivals.
The RDDBEX0956 is for the collector who is bored of the waiting lists and the 'safe' choices. It is for the person who wants to see the mechanical soul of their watch every time they check the time. It is bold, it is technically brilliant, and surprisingly, it is a joy to wear every day. If your wrist can handle the 50.5mm span and your ego can handle the attention, there are few watches that offer this much 'wow' factor while still being a serious piece of horology.
