Hands-on - The Perpetual Motions of the Roger Dubuis Orbis in Machina Central Monotourbillon

Modern watches made by Roger Dubuis are the antithesis of understatement and always manage to deliver a compelling mix of traditional horological content with a dash of extravagant, expressive design. This year’s releases focused on the flying tourbillon, culminating in the Orbis in Machina model with its rare, centrally mounted regulator (only a few can […]

The A. Lange & Söhne Datograph Perpetual Tourbillon Honeygold “Lumen” is a True Super Watch

Each year at Watches & Wonders, we see a handful of novelties that I think can fairly be described as Super Watches. These are the truly audacious creations that are, effectively, out of reach for all but that 1% of the 1% that has the coin and the inclination to buy into something incredibly niche, that’s incredibly expensive, that (honestly) might be years away from actually being produced and successfully delivered. The Grand Seiko Kodo, I think, is a good example of a Super Watch. It stopped everyone in their tracks, had an eye watering price point, and was the ultimate artistic and mechanical expression of the brand that made it. This year had a few Super Watch candidates (including another Kodo) but I think the winner walking away was a watch from A. Lange & Söhne that took the radical step of combining all the things people love about the brand into one watch. A Super Watch, if you will.  The Datograph Perpetual Tourbillon Honeygold “Lumen” was easily my favorite watch name to say aloud during the show. When someone would ask me what my favorite watch of the week was (a question you’re asked about fifty times per day, minimum) I’d reflexively say “Oh, the Lange,” and then continue, probably looking skyward while counting out the watch’s cumbersome title on my fingers, like a school kid figuring out a math problem, “the Datograph, perpetual, tourbillon, lumen,” (I’d always screw it up here) “in honeygold!” I’d be really proud of myself f...

IWC is Thinking Very Far Ahead with their New Portugieser Eternal Calendar

Watches that do more than a human being is capable of are nothing new. Rolex, Omega, and others make dive watches that are capable of reaching depths that no man or woman could survive. The Rolex Deepsea Challenge is rated to 11,000 meters (which means it’s tested to even greater depths) while the deepest point in the ocean is about 10,900 meters, give or take. That means this particular dive watch can go deeper than any depth possible on the planet. Even that, somehow, feels more practical than IWC’s big release at Watches & Wonders, the Portugieser Eternal Calendar. This is the brand’s first secular calendar, which accounts for leap-year exception rules in the Gregorian calendar that play out over a 400 year span. A calendar complication that no living human will have a chance to observe do its thing in real time is one thing, but it’s the moonphase on this watch that is truly looking ahead: IWC claims it’s accurate to 45 million years. And just think, it wasn’t even ten years ago that the Apple Watch had many in this industry scared that watchmaking could be killed by smart-gadgets. Talk about confidence.  The concept of a secular calendar will be worth a refresher for many, as it’s a truly rare complication that most brands simply don’t attempt given the incredibly long timeframes involved (the last one we discussed in these pages was from indie Furlan Marri). The gist is this: in addition to a leap year every four years, Gregorian calendar needs an ad...
