The Jaeger-leCoultre Polaris Perpetual Calendar introduces the in-house calibre 868 which automatically takes into account the irregular lengths of the months and the occurrence of leap years.
The date, month and day indicators are at 9, 12 and 3 o’clock respectively, and the moon phases are at 6 o’clock – a retrograde display for the Southern Hemisphere framing a classical display for its Northern counterpart.
