A. Lange & Sohne isn’t known for being lazy when it comes to complications and the execution of its watches. It isn’t one of the most revered watchmakers from Germany without reason. We all know that ALS is capable of manufacturing some of the most complex, desirable watches, which include some superb chronographs. Among the special edition models the brand introduced last year to celebrate the establishment of Ferdinand Adolph Lange's watchmaking company in Glashutte 175 years ago, one is clearly next level. We reviewed this Tourbograph Perpetual Honeygold already, with photos. But a watch of this visual and mechanical complexity deserves more attention, so here it is in front of our camera.?What is this watch? To put it simply, a hand-wound split-seconds chronograph with a tourbillon regulator, a fusee-and-chain transmission for constant force and a perpetual calendar, all cased in the brand’s rare and proprietary gold alloy with a fascinating dial and impeccably executed finishings. Apart from the ultra-rare Grand Complication?of 2013, this is one of the most complex watches ever made by?A. Lange & Sohne. The kind of watch that not only combines functions but also focuses on chronometry, a specific field that we particularly love here at MONOCHROME, being the essence of watchmaking.

And, as you would expect, it is not a small watch either. But the moment you turn the watch over and look at what is under the sapphire caseback, you cannot but be impressed.With all these delights on board, we thought that in addition to our in-depth article about this masterpiece, a video render more justice to the Tourbograph Perpetual Honeygold. Seeing the tourbillon rotating, playing with the rattrapante chronograph, diving into this incredible movement… We hope you enjoy the video as much as we enjoyed filming it.For more details, read our review here and visit www.alange-soehne.com.
