True greatness

The GRAND LANGE 1 owes its elegance not only to the harmonious dial layout but also to its slender silhouette. With a diameter of 41.0 millimetres, the case is only 8.8 millimetres high – a well-balanced ratio of diameter to height. To assure the maximum rate accuracy of the manually wound L095.1 calibre, it is endowed with a balance spring developed and manufactured in-house.

The GRAND LANGE 1 owes its elegant appearance to the harmonious dial design.
The GRAND LANGE 1 has the largest outsize date of all Lange watches to date.

During the development of the GRAND LANGE 1 presented in 2012, the objective was to transpose the face and the harmonious proportions of the LANGE 1 to this model which is 2.5 millimetres larger. In this undertaking, the engineers chose an uncommonly complex path: they first designed the optimised arrangement of the displays and then developed a custom movement that accommodated the architecture of the dial down to the very last detail.
