The star of the show, in my humble opinion, is the Datograph Perpetual Tourbillon ‘Lumen’ Honeygold Reference 740.055FE. This was the jaw-dropper novelty at last year’s Watches and Wonders, in celebration of 25 years of the Datograph and 30 years of the brand’s rebirth. The release combined many of the brand’s greatest hits into one single watch—the proprietary Honeygold alloy, the absolute monster of the L952.4 caliber, and, of course, the iconic Lumen treatment in its multi-layered sapphire and luminescent construction. However, as epic as the list is, it might have been one of the brand’s most controversial releases due to the price: an eye-watering $620,000, which firmly placed the Datograph Perpetual Tourbillon ‘Lumen’ as Lange’s most expensive serially produced watch to date.
