The Captain Windsor Annual Calendar watch is a joint effort between Zenith and the Musee Internationale Dโhorlogerie. The two entities have produced a unique piece that has wowed the watch world. The Captain Winsor Annual Calendar watch features a calendar system, which indicates the date, day of the week, and the month. The calendar system, amazingly, only requires one adjustment per year (most likely for Februaryโs irregularities). The creator of this spectacular complication is the curator of the MIH.
The annual calendar complication is comprised of three concentric rings โ one each for the date, day, and the month. The outermost disc is responsible for the date, while the middle disc indicates the month, and the last disc displays the day. The construction of this complication uses only 9 moving parts. This not only enhances the stability of the complication but also its accuracy.
Naturally, this watch is fitted with Zenithโs award winning, high frequency movement โ the El Primero. The El Primero is self-winding and beats at the high frequency of 36,000 vibrations per hour. This allows the timepiece to time smaller intervals of seconds and so has a higher degree of accuracy. This is the first time that a high frequency movement has been paired with an annual calendar.
The case is made from 18kt rose gold which has been polished, giving the watch an understated appeal. The case back is transparent allowing for the viewing of the movement. The main crown on this watch is ridged for the effortless adjustment of the time and annual calendar.
The dial is white and carries applied rose gold Arabic numeral hour markers. In fact, all of the elements are either in rose gold or are bordered in rose gold, with the exceptions of the central chrono seconds hand and the small seconds indicator both of which are crafted from blued steel. The Zenith Captain Winsor Annual Calendar is fitted with a dark brown alligator leather strap and is secured by a traditional pin buckle.
