The Little Lange 1 Moon Phase comes with a guilloché

silver-toned dial inside a pink gold case. The moon disc, which is also

silver-coloured, is inscribed with two golden moons. This astronomical

complication reproduces the synodic orbit so accurately that after 122.6 years

it will differ from the actual position of the moon by just one day. The new,

manual-wind L121.2 calibre, on the base of The Lange 1 movement introduced two

years ago, includes a twin barrel to deliver a 72-hour power reserve, and a

large, cam-poised balance with in-house balance spring. The balance cock is

hand-engraved, one of the hallmarks of an A. Lange & Söhne watch.
