To celebrate the 175th anniversary of the founding of A. Lange & Söhne, the German horological powerhouse has released a new collection of timepieces belonging to the 1815 family that pays homage to its founder Ferdinand Adolph Lange. The most important of them is the limited edition A. Lange & Söhne Tourbograph Perpetual Honeygold “Homage to F. A. Lange” which was revealed at the Watches & Wonders exhibition in Shanghai along with the other homage watches. If you look closely, you’ll realize that the limited-edition is basically a new iteration of the spectacular Tourbograph Perpetual ‘Pour Le Mérite watch from 2017 that presents a combination of five complications in a very traditional A. Lange & Söhne package. The latest version that will be available only in very small numbers offers the timepiece in the brand’s unique 18k gold alloy, usually reserved for special editions, along with a proprietary material used for the dial.
Starting with the aesthetics of the limited-edition, the overall design has remained pretty much unchanged, including the extremely complex dial. The case measures 43mm in diameter and a height of 16.6mm; what’s new is the case material which is the brand’s proprietary Honeygold 18k yellow gold alloy that has only been used on a handful of releases since its creation in 2010. Although A. Lange & Söhne has never revealed the alloy’s details, it is touted as a significantly more scratch-resistant material over normal 18k gold. Moving to the dial, the watch makes use of relief-engraved Arabic numerals with an outer railway-track scale and characteristic gold alpha hands, all of which are also in 18k Honeygold alloy. Offering a stunning contrast is the gray rhodium finish of the dial, which gives it a very three-dimensional look.
Despite the long list of complications offered on the watch, the dial is free of clutter thanks to each sub-dial performing double-duty. The larger subdial at 12 o’clock houses both the moonphase display and an outer pointer date ring, while the subdial at 9 o’clock has a combination of pointer day and chronograph minutes. At t 3 o’clock are the month and leap year indicators and the oversized tourbillon aperture at 6 o’clock provides a beautiful balance to the dial along with offering a stunning view of the movement. The manufacture L133.1 handwound movement combines some of the most complex horological engineering masterpieces with centuries-old watchmaking concepts. Just about every element of the extremely complicated movement is very, very impressive. The movement offers 36 hours of power reserve at a 21,600 bph beat rate. Only 50 examples of the Tourbograph Perpetual will be made with each piece costing approximately 500,000 Euros ($ 592,000).
