A. Lange & Söhne Richard Lange Perpetual Calendar Terraluna

Owners widely praise the A. Lange & Söhne Richard Lange Perpetual Calendar Terraluna's horological brilliance, specifically its orbital moonphase complication accurate for over 1,000 years and the perpetual calendar. The manual-wind movement with twin barrels providing a 14-day power reserve and constant force escapement is also a significant draw. However, owners and reviewers consistently flag the A. Lange & Söhne Richard Lange Perpetual Calendar Terraluna as a very large watch, measuring 45.5mm and over 16mm thick, which some find difficult for daily wear or fitting under a cuff, leading to recommendations to try it on before purchase. On balance, owners and reviewers rate the A. Lange & Söhne Richard Lange Perpetual Calendar Terraluna highly for its impressive complications and movement finishing, despite its substantial dimensions.
