About this caliber

Self-winding movement with small seconds and indicators for both the day as well as the [big] date. This was introduced in 2019 with the Odysseus watch. A. Lange & Söhne developed the new L155.1 DATOMATIC manufacture calibre. The name DATOMATIC visible on the rotor stands for the date mechanism combined with automatic winding. With a diameter of 32.9 millimetres, the movement – visible through the sapphire-crystal caseback – completely fills the case. It features a unidirectionally winding central rotor with a centrifugal mass in platinum. Thanks to the skeletonization of the rotor further details of the manually executed, lavish finissage of the movement can be observed.
