A. Lange & Söhne Wows With 1815 Tourbillon

A tourbillon is a tourbillon is a tourbillon—more than 224 years after its invention by the visionary watchmaker Abraham-Louis Breguet, the intricate mechanism continues to captivate enthusiasts around the world. With the latest edition of the 1815 Tourbillon, A. Lange & Söhne once again places this fascination at the center of attention. Combining refined technical features with the highest level of craftsmanship, the timepiece now takes on an even more dramatic presence thanks to a deep black, in-house-crafted grand feu enamel dial that provides a breathtaking stage for the "whirlwind" through a generous aperture at 6 o’clock. By constantly changing the position of the balance, the rotating cage compensates for the effect of gravity on the oscillation system, thus enhancing rate accuracy. Yet, Lange's approach goes further than tradition. The complication features two innovative functions that increase its precision: a stop-seconds mechanism that allows the watch to be halted by pulling the crown, and a Zero-Reset system that ensures the seconds hand instantly jumps to zero. Together, they allow the time to be set with absolute accuracy, down to the minute marker.

The 1815 Tourbillon expresses its artistry in every carefully executed detail. The bridge and the upper section of the cage are finished with elaborate black polish, a time-intensive technique that produces a flawless surface shifting between mirror-like reflection and deep black depending on the angle of light. The dial itself is a testament to patience and skill. Beginning with a white-gold base, enamel pigments are crushed, applied, and fired multiple times, followed by meticulous surface finishing. Each dial requires over one hundred individual steps and several weeks of work. The chamfered aperture for the tourbillon adds yet another level of difficulty, demanding the highest dexterity to avoid damaging the delicate enamel. The result is a dial of extraordinary depth and clarity, where crisp white markings, Arabic numerals, and a railway-track minute scale – hallmarks of the 1815 family – stand in sharp contrast against the radiant black background.

Through the sapphire case back, the manufacture caliber L102.1 reveals itself as a feast for the eyes. In typical Lange fashion, the movement is assembled twice, ensuring not only flawless function but also immaculate finishing down to the smallest detail. Its freely oscillating Lange balance spring and traditional screw balance guarantee stable rate accuracy throughout the 72-hour power reserve. Every glance brings new facets of its beauty to the fore: the three-quarter plate in untreated German silver, the hand-engraved balance cock, and the diamond endstone in a gold chaton at the heart of the tourbillon, a traditional element that A. Lange & Söhne once equipped its most precious 1A-quality watches with.

With its 39.5mm platinum case and a height of 11.3mm, the new edition, which is the fifth variant since its debut in 2014, fits elegantly on the wrist. It is equipped with a black alligator leather strap. Pricing is available on request.
