The Zeitwerk Decimal Strike makes time audible in a new way: its striking mechanism sounds every ten minutes.
The Zeitwerk Decimal Strike belongs to the illustrious Zeitwerk family, first introduced in 2009. It gave time a new face with a mechanical jumping numerals display. Given its mechanical architecture, the ZEITWERK calibre offers ideal prerequisites for the integration of a striking mechanism. Building on that strength, this watch features an acoustic time indication.
A. Lange & Söhne – Zeitwerk Decimal Strike
Where the music sounds
Two tuned gongs indicate the full hours as well as the ten-minute intervals between the start of one hour and the next. The two hammers that are visible on the dial side consist of polished steel and, like the hammer bridge, are decorated with a tremblage engraving. The hammer on the left strikes the low-pitched gong once every full hour. The right-hand hammer sounds a higher-pitched tone every ten minutes, or in other words, every time a new ten-minute interval begins.
With its large, precisely jumping numerals display, the Zeitwerk Decimal Strike assures excellent legibility. In one-minute intervals, the units disc instantly advances by exactly one increment. The patented constant-force escapement between the mainspring barrel and the balance delivers the power. It makes sure that the balance has a constant amount of energy across the entire power reserve period. The high-pitched tone sounds every time the tens disc advances; at the start of the hour, when the low-pitched tone is struck, all three numeral discs jump synchronously by one increment. The striking mechanism can be switched off. When the button at 4 o’clock is pressed, the hammers are deflected away from the gongs. This also happens when the crown is pulled to set the time.
The watch has a diameter of 44.2 millimetres. The lavishly finished, manually wound calibre L043.7 has a maximum power reserve of 36 hours. Lange-typical quality hallmarks include the three-quarter plate made of untreated German silver and decorated with Glashütte ribbing, the hand-engraved balance cock, and a cam poised balance with a free-sprung hairspring crafted in-house.
The case of this timepiece, limited to an edition of 100, consists of honey gold as used exclusively by A. Lange & Söhne.
A tribute to fine watchmaking, the Zeitwerk Decimal Strike is a veritable piece to enhance a much-loved collection!
