A. Lange & Söhne presents the new ZEITWERK MINUTE REPEATER in a limited edition of 30 pieces with a gray dial and honey gold-colored case (HONEYGOLD®), a Lange exclusive that gives the timepiece an unmistakable sound. The ZEITWERK MINUTE REPEATER is a one-of-a-kind watch, known for its distinctive jumping digit display and decimal minute repeater function.


In 2015, A. Lange & Söhne introduced a completely innovative interpretation of the classic watchmaking complication with its ZEITWERK MINUTE REPEATER model in platinum. This watch is equipped with a highly sophisticated mechanism that allows it to strike the time on demand. However, what makes it truly extraordinary is the way its sound mechanism integrates seamlessly with the mechanical-digital time display.

Unlike traditional repeating watches that strike every quarter of an hour, the mechanism of the ZEITWERK MINUTE REPEATER strikes at ten-minute intervals, a complication originally conceived by Monsieur Breguet in the past. This means that the sound emitted corresponds exactly to the time indication on the digital dial. When you press the button at 10 o'clock, the mechanism produces a low tone for every hour that passes, a double tone (high/low) for every ten minutes and a high tone for every single minute. For example, if the time reads 6:53, you will hear a sequence of six low-pitched gong strikes, followed by five high-pitched strikes, and finally three more high-pitched strikes.

In this edition of the ZEITWERK MINUTE REPEATER, the acoustic time indication has been significantly improved with the introduction of an originally expressive sound. The case, made with the special honey-colored gold alloy, plays a fundamental role as a resonant body, giving the sound unique quality and characteristics. The result is a crystal clear and engaging sound, with a warm and enveloping tone.

The ZEITWERK MINUTE REPEATER stands out for its innovative button mechanics used to activate the chime. In this watch, the energy required for the striking is supplied directly from the barrel, thus eliminating the need for a lever usually used to wind a separate mainspring.

To ensure flawless interaction in this complex mechanism, sophisticated safety and locking mechanisms have been integrated into the movement. In order to avoid premature interruptions in the repeating sequence and accidental stopping of the watch, the alarm cannot be activated if the remaining power reserve is less than twelve hours. This critical state is indicated on the power reserve indicator by a red dot positioned at 12 hours.

When the alarm is active, the advancement of the digit disc is temporarily delayed and the extraction of the crown is blocked. This ensures that the repeating sequence and audible timekeeping are not affected. The maximum chiming sequence, which occurs at 12.59, lasts approximately 20 seconds. If a new minute begins in the meantime, the jump in minutes or hours is recovered immediately. Subsequent advancement of the digit disc resumes regularly when the second hand passes the 60-second mark.


The Caliber L043.5

As in all variants of the ZEITWERK watch family, the Manufacture caliber L043.5 is equipped with a sophisticated tension mechanism positioned between the barrel and the balance wheel. This mechanism not only provides the energy necessary for the precise advancement of the digit disc at one-minute intervals, but contributes significantly to the stability of the watch. It ensures that the balance wheel receives a constant pulse, regardless of the state of charge of the watch, thus ensuring smooth running over time.

This movement is made up of an impressive total of 771 components, each of which has been meticulously hand-finished with dedication and craftsmanship. Precision and attention to detail are evident not only in the functionality of the movement but also in the beauty of its finishing. Both the balance cock and the lever escapement bridge are hand-engraved in filigree.
