Jaeger-LeCoultre Perpetual Calendar Blue Dials

Key Points from the Discussion

• The date adjustment on some perpetual calendars is linked to the hour hand, requiring a full 24-hour rotation for each date change, which can be a tedious process.
• A key question for collectors is whether any perpetual calendar movements allow for backward date adjustment, a feature that would significantly enhance user convenience.
• While date adjustment can be cumbersome, rip9er notes that adjusting the time backward is generally possible on these watches.
• A general rule for watches with date functions is to avoid turning the time backward during the period when the date mechanism is actively engaged, to prevent potential damage.
• This thread is discussion-light, with the original author providing most of the substantive content and observations.
