The calendars present in haute horlogerie movements are mainly two: the Perpetual Calendar and the Annual Calendar.
Often confused with each other, these complications are a very important element to consider in a movement, and for anyone who decides to buy a watch the difference must be clear.
The Perpetual Calendar can be found in watches where at least date and month are indicated. It stands out because it considers variable durations of months and leap years.
Moreover, on the dial of a watch with Perpetual Calendar, we can usually find also the day of the week, the year and the moon phases indicated.
Therefore we can say that the Perpetual Calendar is considered the most completed and the most coveted complication. It is the Calendar most comfortable and practical as it never needs to be adjusted.
We speak of the Annual Calendar when the watch, which shows days and months, has a movement that always consider the duration of the months, but not the leap years.
For this reason, an Annual Calendar watch must be adjusted every year on March 1st, using the crown.
Undoubtedly both are absolutely excellent haute horlogerie complications, and whoever has to choose between the two will be, however, amply satisfied.
