The most impressive novelty from A. Lange & Söhne this year at Watches & Wonders 2025 is the new Minute Repeater Perpetual with a black enamel dial. This horological masterpiece brilliantly marries the acoustic precision of a minute repeater with the mathematical complexity of a perpetual calendar. Either complication standing alone would represent a significant technical achievement; their integration into a single timepiece presents an extraordinary challenge that demands exceptional expertise from both engineers and watchmakers.
The harmonization of these mechanisms requires consummate skill to ensure that the calendar's intricate mechanics operate flawlessly while maintaining the pure, crystalline sound of the repeater's chimes—a testament to Lange's uncompromising commitment to horological excellence.
The meticulously finished timepiece features an in-house crafted enamel dial and comes in a limited edition of 50 pieces in platinum with a case diameter of 40.5 mm and a thickness of 12.1 mm. Despite its solid platinum construction, the watch is not very top-heavy with a weight of 157 grams only.
The new A. Lange & Söhne Minute Repeater Perpetual delivers crystal-clear sound through meticulously hand-tuned gongs harmonized with the platinum case's acoustic properties. When activated via the case's integrated slide, the chiming mechanism strikes hours at a low pitch, quarter hours with a double tone, and minutes with a higher-pitched tone.
Things to Know About the Watch
Creating this minute repeater demands extraordinary craftsmanship. A master watchmaker harmonizes all components through multiple cycles of adaptation and testing, paying particular attention to the hammers' material, shape, size, weight, hardness, and strike—much like tuning a piano. The striking mechanism on this new Minute Repeater Perpetual also incorporates sophisticated features including:
Pause elimination that skips intervals between hour and minute strikes when no quarter-hour tone is struck
Safety mechanisms preventing simultaneous activation of the minute repeater and crown
Patented hammer blocker causing hammers to dwell briefly in their home position, preventing inadvertent double strikes
While the minute repeater announces the present moment, the perpetual calendar extends into the future, displaying the precise date, day, and month while accounting for leap years. The calendar requires adjustment only once on March 1, 2100, when the leap year is skipped per the Gregorian calendar. The moon-phase display accurately replicates the lunar orbit, requiring correction only once every 122.6 years. Despite this complexity, all calendar indications can be advanced simultaneously with a single corrector.
The four-part white gold dial features black enamel filling, providing an elegant backdrop for the signature Lange outsize date and other displays. The subsidiary dial at 6 o'clock houses the small seconds and moon-phase display, with gold moons surrounded by over 100 hand-engraved stars. Fine white gold circular surrounds separate the dial sections and allow for better readability.
The Movement
Turning the watch over reveals the German silver solid manual wound calibre L122.2. This newly developed 640-part manual wound movement includes a free-hand engraved balance cock with whiplash spring, a German silver three-quarter plate with black-rhodium engravings, four screwed gold chatons on a grained surface, manually bent gongs with black-polished hammers, solarization decoration on the barrel, centrifugal-governor, and gong hammer bridges and overhung centrifugal governor ensuring uniform strike cadence.
On the Wrist & Price
On the wrist, the A. Lange & Söhne Minute Repeater Perpetual commands attention without being too overwhelming. Its 40.5 mm platinum case provides the perfect balance between presence and wearability for the discerning collector. The relatively thin 12.1 mm profile sits with purposeful elegance against the skin, its weight a constant, reassuring reminder of the 640-part mechanical symphony housed within.
