A. Lange & Söhne Complications Overview

Key Points from the Discussion

• The A. Lange & Söhne Datograph Perpetual Tourbillon (Ref. 410.030) features the in-house caliber L952.1, comprising 556 components. This movement masterfully integrates a split-seconds chronograph with a perpetual calendar, creating a visually complex and mechanically sophisticated 'city underneath the sapphire'.
• A key design feature is the outsized Lange date. The perpetual calendar functions can be adjusted via a single rectangular pusher at 10 o'clock (with the crown pulled out), ensuring user-friendly setting even for future leap years like March 1, 2100. Individual recessed pushers allow fine-tuning of day, month, and moon phase.
• The specific reference, 410.030, is the grey dial white gold version, featuring a sterling silver dial with applied hour markers.
• For some collectors, the pursuit of new watches and unexpected horological discoveries is what keeps the passion alive, even after achieving initial collection goals.
