The A. Lange & Söhne, 1815 Emil Lange Moonphase, reference 231.035 was introduced in 1999 to commemorate the 150th anniversary of Emil Lange’s birthday, son of the founder Ferdinand Lange. Following in his father’s footsteps, he continued his legacy in watchmaking, producing some of the most sophisticated and complicated timepieces available at the time. Produced in a limited series of 150 pieces in platinum and a 250 pieces in pink gold was the brands first wristwatch to feature moonphases.

The present example in platinum and numbered 108/150, is offered in overall very good condition and displays seven applied 18K white gold appliques forming the Big Dipper constellation on the dial, one of the most distinctive asterisms in the universe. The moon phase demonstrates A. Lange & Söhne’s technical skill with a movement, which automatically adjusts twice a day and will only deviate from the orbital position by one day after 1058 years. The reference sold out quickly when first released.
