  • Catalogue Essay

    Produced to commemorate the 150th anniversary of Emil Lange’s birth in 1999, the present watch was made in a limited edition of 250 examples in pink gold. The black dial depicts the Big Dipper constellation, which is one of the most distinctive asterisms in the sky. To further highlight the astronomical theme, the hour markers at 3, 6 and 9 o’clock are replaced with applied stars. The moon phase is automatically adjusted twice a day and is exactly calculated to deviate only one day from the moon’s actual orbit in 1,000 years.

  • Artist Biography

    A. Lange & Söhne

    German • 1845

    Originally founded in 1845 by Ferdinand Adolph Lange in Glashütte, Dresden, Germany, the firm established an entire watchmaking culture and industry in Glashütte. The brand quickly became Germany's finest watchmaker, first creating dependable, easy-to-repair watches before going on to produce some of the world's finest complicated pocket watches, including Grande Sonnerie watches, tourbillon watches and Grande Complications.

    On the final day of World War II, their factories were destroyed by Russian bombers, and in 1948 the brand was confiscated by the Soviet Union. Following the fall of the Berlin Wall in 1990, Ferdinand's great grandson Walter Lange re-established the brand with the objective to once again produce top-quality luxury watches. Now part of the Richemont Group, its original vintage and modern creations are highly coveted by collectors. Key models from the modern era include the Lange 1, Pour Le Mérite Tourbillon and the Zeitwerk.
