While the luminous treatment transforms the appearance of the watch at night, it is equally mesmerising in daylight. The contrast between the translucent monochromatic dial and the soft, warm tones of the Honeygold case and dial furniture is unusual and very beautiful.
This makes it the fourteenth Lange watch and the second Lumen model to be dressed up in the company’s proprietary alloy. While the exact composition remains a secret, Honeygold is known to be o be nearly twice as hard as standard gold alloys and more durable than platinum. Its gentle, pleasing tone is incomparable; it is neither as rosy as rose gold nor as brassy as yellow gold.
The case measures 41.5mm in diameter, just 0.5mm larger than the Datograph Up/Down, and has a height of 14.6mm. It is no doubt a thick watch, but a watch with three traditionally executed complications was never intended to be an exercise in ultra-thin watchmaking and the height-to-width aspect ratio actually feels quite harmonious. In addition, it has a thick, polished domed bezel and a raised flange on the case back to accommodate the movement, resulting in a relatively slender case middle, which is further emphasized with a contrasting satin-brushed finish.
Dressed to the nines
As with almost all Lange chronographs, the view on the back of the watch is arresting to the point that it’s become cliché to say so. One of the most obvious traits that distinguishes it from other chronographs is its unassuming density. Not just levers, but also springs are shaped into elegant forms that exhibit a narrow profile in plan view but with substantial height in cross-sectional view. The clutch lever alone is particularly elaborate. It consist of a lower and upper part assembled by a screw. Its semi-circular pivot moves around a jewel setting screwed to the drive wheel bridge that sits above the plane of the column wheel, thus the clutch lever requires two levels to reach the column wheel. While this is purely functional, both parts are visible and decorated, and the upper part forms a complex shape that lends itself to two sharp internal angles.
