A. Lange & Söhne 2020 Acquisitions

Key Points from the Discussion

• The A. Lange & Söhne Richard Lange Pour le Mérite (PLM) features a fusée and chain mechanism, which comprises over 900 components, exceeding the part count of many Grand Complication pieces like tourbillons or minute repeaters, despite its svelte 40.5mm case.
• The PLM's 'stealth' appeal lies in its visual similarity to a standard Richard Lange, making its complex fusée and chain mechanism a secret known primarily to the owner, unlike Patek Philippe, which often inscribes 'Tourbillon' on dials.
• A fusée and chain mechanism ensures constant torque delivery throughout the power reserve, a capability not matched by multiple barrels alone, which only distribute torque equally but cannot maintain it as power depletes.
• The true measure of the PLM's performance should be its isochronism, not just overall accuracy, given its chronometry-focused design.
• The A. Lange & Söhne Richard Lange Pour le Mérite is praised for its understated aesthetic, often described as a 'down to earth look' for a horological masterpiece, embodying a 'if you know, you know' appeal.
• The PLM's accuracy is reported to be within 1 second per day when worn, with a power reserve extending to 64 hours, surpassing the advertised 56 hours.
