Introducing A. Lange & Söhne Unveils the Minute Repeater Perpetual

At Watches and Wonders 2025, A. Lange & Söhne once again launches a watch with a minute repeater, this time pairing it with a perpetual calendar. Each of these complications alone represents a technical feat; the combination of the two, however, poses an even greater challenge.

As with all Lange watches featuring a striking mechanism, the Minute Repeater Perpetual is designed to meet superb acoustic quality standards and boasts a unique timbre. A lucid, clear, and reverberant sound is assured by the hand-tuned gongs that harmonize perfectly with the acoustic characteristics of platinum, the case material. Completing a minute repeater is highly elaborate, requiring acute hearing and extreme dexterity. All components are carefully harmonized by a Lange master watchmaker through multiple cycles of adaptation, disassembly, reworking, reassembly, and rigorous testing. For the hammers, key factors such as material, shape, size, weight, and hardness are meticulously considered.

With a case diameter of 40.5 millimeters and a height of 12.1 millimeters, the watch is equipped with a safety device to prevent damage to the chiming mechanism. This ensures that the minute repeater cannot be activated while the crown is pulled, and conversely, the crown cannot be pulled when the chiming mechanism is active.

The four-part dial, made of white gold and filled with black enamel, is crafted in the A. Lange & Söhne manufacture through a time-consuming process. The immaculate, glossy black surface provides an elegant stage for the displays and the characteristic Lange outsize date, offering a contrasting backdrop that ensures excellent legibility.

The subsidiary dial at 9 o’clock accommodates the day-of-week and 24-hour displays, while a second dial at 3 o’clock features the month and leap-year indications. A third subsidiary dial at 6 o’clock showcases the small seconds and the moon-phase display. Both moons, crafted from 750 gold, are surrounded by more than 100 hand-engraved stars.

This exceptional timepiece exhibits another distinctive detail: all four dial sections are embellished with a circular lesene, a fine border in white gold. On the main dial, it runs between the outsize date and the Roman numerals, while on the subsidiary dials, the lesenes separate the inner display sections from the outer ones.

The sapphire-crystal caseback provides fascinating insights into the technical complexity and the high level of finishing of the newly developed Lange manufacture calibre L122.2. All 640 parts of the manually wound movement reflect the meticulous craftsmanship associated with A. Lange & Söhne. The three-quarter plate made of untreated German silver is decorated with black-rhodiumed engravings, while four screwed gold chatons adorn its grained surface.

Although most of the repeater and perpetual calendar mechanisms lie concealed below the dial, the most important elements of the striking mechanism, the two manually bent gongs framing the movement and the two gong hammers, are resplendent in their beauty. The hammers provide an additional focal point, finished with an exquisite black polish. The movement beats at 3 hertz, and the mainspring barrel delivers a maximum power reserve of 72 hours.

The platinum Minute Repeater Perpetual is worn on a black, hand-stitched alligator leather strap with a deployant platinum buckle. This exceptional timepiece is limited to 50 pieces.
