A. Lange & Söhne

The A. Lange & Söhne Reference 231.031, known as the 1815 Moonphase "Homage to Emil Lange," is an exquisite timepiece that epitomizes the brand’s dedication to horological excellence. This limited-edition watch, introduced in 1999, was created to celebrate the 150th anniversary of A. Lange & Söhne and to honor Emil Lange, the second son of the company's founder, Ferdinand Adolph Lange. Emil Lange was a master watchmaker who played a crucial role in shaping the brand’s legacy of precision and innovation in horology.

The 1815 Moonphase is elegantly housed in a 35.9 mm diameter three-part case, reflecting the meticulous attention to detail that A. Lange & Söhne is renowned for. The dial is stunningly designed, featuring a small seconds subdial at 4 o’clock, a moonphase display at 8 o’clock, and an intricate rendering of the Big Dipper constellation. The moonphase mechanism is a marvel of engineering, designed to remain accurate for an astounding 1,058 years. It accurately simulates the synodic month – the period between successive full moons – which is 29 days, 12 hours, 44 minutes, and 3 seconds. This extraordinary precision pays homage to the intricate craftsmanship of the astronomical clocks of the past.

This timepiece is available in a limited edition of 150 pieces in platinum (Reference 231.035) and 250 pieces in pink gold (Reference 231.031). Each watch is individually numbered, further enhancing its exclusivity and desirability among collectors.

The A. Lange & Söhne 1815 Moonphase "Homage to Emil Lange" is a remarkable blend of historical reverence and advanced horological technology. It stands as a tribute to Emil Lange’s legacy and embodies the brand’s unwavering commitment to precision, craftsmanship, and timeless elegance. This timepiece not only honors a pivotal figure in A. Lange & Söhne’s history but also showcases the brand’s ability to seamlessly merge traditional watchmaking techniques with modern innovations in astronomical accuracy.
