An 18-carat pink gold case is crowned by 52 diamonds on the bezel in the Little Lange 1. The brilliant-set bezels eloquently frame the black iridescence of the mother-of-pearl dial. Pink-gold hands and appliques create an aesthetically convincing contrast in both models. The Lange outsize date with pink-gold aperture surrounds is another eye-catcher. And the overall appearance of both "Soirées" is exquisitely accented with a chestnut strap in leather: due to its pearly structure, this supple material was already coveted during the art deco period. The buckle in solid pink gold is the perfect finishing touch. Despite the fact that its case diameter is only 36 millimetres, the Little Lange 1 “Soirée” is endowed with all the features that define the LANGE 1: Rose gold case with a brown alligator leather strap.
