During my visit with A. Lange & Söhne at SIHH last week, I had an opportunity to snap some images in and around the booth, including a few of the new timepieces. The big story this year is the brand’s 165th anniversary and the three Homage to F.A. Lange pieces in Lange’s proprietary honey gold. The new Annual Calendar was also very well received.

At SIHH, Lange introduced a black-dial version of the Zeitwerk, known internally as the “Phantom”. To be read at night, the Phantom’s numbers must glow, but charging the luminescent material is a challenge when the numbers are hidden behind the dial most of the time. Lange solved the problem by creating the dial from a “reverse sunglasses” material that allows UV light through, but that stops visible light. The dial material is slightly translucent and up close, the movement can be viewed through it, but from more than about 18 inches away, the dial appears black. In the image below, light reflects off the “sunglasses” portion of the dial, making it appear dark blue.
