2. A. Lange & Söhne, Glashütte i/SA, "GROSSE LANGE 1 Luna Mundi - Ursa Major", Movement No. 39075, Case No. 152534, limited edition serial number 34/101, Ref. 119.026, Cal. L901.8
Case: 18k white gold, sapphire glass screwed on back, "Lange" 18k white gold buckle. Dial: solid silver, argenté.
Luna Mundi is a set of watches consisting of "Ursa Major" in a coolish 18K white gold case and "Southern Cross" in a warm 18K pink gold case. Both watches have a continuously running and highly accurate moon phase indication. In most movements that are less sophisticated the moon phase is only adjusted twice a day; A. Lange & Söhne, however, provides a much higher degree of accuracy here with a deviation from the visible lunar orbit of only 1 day in 122.6 years, if the watch is kept running continuously. "Ursa Major" has 398 movement parts and displays the moon phase as seen from the Northern Hemisphere; "Southern Cross" has 402 parts and displays the moon phase as seen from the Southern Hemisphere. The number of movement parts is different because the moon disc for the Northern Hemisphere is rotating clockwise while the one for the Southern Hemisphere is rotating counterclockwise. "Ursa Major" is the first wristwatch to realistically display the waxing and waning of the moon as visible from North of the equator.
