Dials are generally silver or enamel. The designs themselves are also distinctive and unique, making them easily distinguishable from Swiss luxury brands. Produced completely in house, A. Lange & Sohne watches generally display blued screws, individually hand-engraved balance cocks, gold chatons and three-quarter balance plates.
