Perpetual Calendar Watches Collection

Key Points from the Discussion

• The A. Lange & Söhne Datograph Perpetual is frequently cited as a favorite, with its ingenious design and strong collector appeal, despite the brand's price increase policies.
• H. Moser & Cie.'s perpetual calendars are praised for their innovative design and often exceed their stated power reserve, with one owner reporting over 8 days of power.
• A notable drawback of some perpetual calendars, such as the IWC model in the collection, is the inability to adjust the date backward if accidentally advanced, requiring the wearer to wait for the watch to catch up.
• The IWC perpetual calendar, while a significant piece, is noted by some collectors as not fitting seamlessly with the rest of the high-horology pieces in the collection.
• The discussion highlights a collector's dilemma: the joy of owning multiple perpetual calendars, especially for the leap year, versus the practical challenge of wearing and managing a large collection of complicated watches.
• The A. Lange & Söhne 1815 Rattrapante is admired for its epic and romantic appeal, though some express concerns about its readability.
