A. Lange & Söhne unveiled the Zeitwerk Minute Repeater, one of the Saxon haute horologer’s most complicated timepieces, five years ago in a platinum case and silvered dial. For this year’s digital Watches & Wonders launch event, Lange finally rolled out a second version, this one in a white-gold case and a vibrant blue dial, housing the same ultra-complex, in-house-developed chiming mechanism as the original.

The Zeitwerk Minute Repeater is now available in white gold with blue livery.

The Zeitwerk Minute Repeater is the first watch that marries a “digital” time display, with jumping hours and minutes, to a repeater that chimes at 10-minute intervals. The timepiece’s highly legible dial belies the technical complexity behind it. In the classical manner of the Zeitwerk family, which A. Lange & Söhne introduced in 2009, the jumping hours are displayed in a window at 9 o?clock, while the minutes are shown on two disks of different heights at 3 o?clock.
