A. Lange & Söhne 1815 Tourbillon 730.079F Platinum White Dial Limited Edition of 100 (2026)

Limited to 100 pieces, the 1815 Tourbillon 730.079F dresses A. Lange & Söhne's stop-seconds tourbillon in Platinum with a White dial of grand feu enamel, presented in 2018, four years after the model's debut at SIHH 2014. Each case is numbered from 001/100 to 100/100, and each dial requires some 30 manual steps, a traditional craft set against the modern micromechanics that let the tourbillon stop and its seconds reset to zero.

The enamel is fired over a copper base and printed with black Arabic numerals and a red 12, read with blued steel hands. At 6 o'clock an aperture reveals the one-minute tourbillon under a black-polished bridge, the only sign of the complexity inside. The 39.5 mm Platinum case is 11.3 mm high with a sapphire caseback, and the watch is fitted to a black alligator strap with a Platinum deployant buckle.
