This 18ct white gold Saxonia Moon Phase is beautifully proportioned. 

In new condition, this 40mm self-winding Moon Phase was purchased in late 2020 and is supplied with its A. Lange certificate of origin, correction stylus, booklets, box and 2-year manufaturer's warranty from the date of original sale. The impressive white gold case merges with a pure silvery white dial, punctuated only by the perfectly symmetrical double-digit calendar apertures and rich blue night sky of the moon disc.
The dial is made of solid silver finished in a frosting that Lange calls argenté. Hands and hour chapter markers are in solid white gold, and are of a restrained but legible weight.
Lange is rightly proud of the precision of their lunar wheel train, which would only need correction by 1 day in 122.6 years. Automatic winding, using a large platinum-edged winding rotor.
