IWC Annual Calendar:
The New Small Eternity

The new IWC Annual Calendar with the 52850 in-house movement reduces the calendar problem to a single manual adjustment at the end of February. And that‘s it.

Ask watchmakers, and one thing is soon clear: their favourite complication is the tourbillon.

A matter of adjustment

For an IWC watch to run accurately, the oscillations of the balance require careful adjustment.

A mechanical watch continues to show the correct time even as the tension in the mainspring diminishes. Making this possible is a mechanism that has been gradually improved for over 300 years: the escapement.

Time moves the world. The IWC Portuguese Grande Complication is an understated, beautifully designed way of summarizing time as the motor of all change: a time machine that shows a tilted globe on the dial. The depiction also references the historic background of the Portuguese, a nation of fearless seafarers who gave their name to the watch family.

The Arabic numeral appliqués and the railway-track-style chapter ring are signature elements of the Portuguese watch family. The dial features elegant, feuille-style hands that show the hours and minutes, together with a slim chronograph hand that shows stop times in seconds.

In this tiny window, two discs and a century slide show the correct year in four digits without any help from the user until 2299 – even until 2499 after exchanging the century slide. The day of the week and the seconds are displayed in a subdial at 9 o’clock.

Small, but no less important: the blued hand at 3 o’clock shows the date correctly even in months with fewer than 31 days and in leap years – until the year 2100. The months and stop times in hours recorded by the chronograph are shown in a combined totalizer at 6 o’clock.

When it comes to the moon, the Grande Complication is no less accurate: the display deviates from the actual progress of the moon by just one day in over 500 years. The disc completes one rotation in two full lunar periods. The same display shows stop times up to 30 minutes.

Portuguese Grande Complication, Ref. 3774, in a platinum or red-gold case, limited to 100 watches per year. Self-winding, perpetual calendar showing the date, day, month, and the four-digit year. Perpetual moon phase display. Stopwatch function with aggregate timing up to 12 hours. Minute repeater for the time in hours, quarters and minutes. It only takes a 45 mm diameter and a 16.5 mm height to house such a complicated world.
