Montblanc MB LL100.1

MB LL100.1 is an automatic in-house movement manufactured by Montblanc at its Le Locle manufacture. It features an exotourbillon complication, with the tourbillon carriage positioned outside the balance wheel rather than integrated within it, a configuration that reduces the mass on the balance for improved efficiency. The movement belongs to the MB LLxxx family and is used in Star Legacy Exotourbillon models. It remains in production.
