Zenith’s new Captain Winsor Annual Calendar brings together two notable watchmaking achievements: the elegantly simple annual calendar complication and Zenith’s famous 36,000 vph in-house El Primero chronograph.
The Captain Winsor Annual Calendar begins with Zenith’s El Primero automatic chronograph movement, produced by the* **manufacture* in-house for more than 40 years. The El Primero is the only series-produced movement
to beat at 36,000 vibrations per hour.
The movement is decorated with *côtes de genève* and circular-graining, which is visible through the rose gold case set with baguette-cut diamonds coupled with brown alligator leather strap and a rose gold pin buckle.
To this caliber Zenith adds ingenious complication, which displays the days of the week, date and month and that requires only one adjustment per year. To ensure excellent readability, the display is provided by three concentric discs. The outer disc shows the date, the middle one the month and the inner one the day of the week. This mechanism is both simple and complex: for 31-day months, the date disc moves the month disc forward; for
30-day months, the month disc makes the 31 “jump”. The minimalist design of this complication comprises just nine moving parts, whereas most calendars require between 30 and 40. The only manual adjustment the watch requires is for the transition from February to March.
