Annual Calendar coupled with the legendary El Primero Chronograph

Background:  Named Captain Winsor Annual Calendar, this timepiece marks the start of a collaboration between the Musée International d’Horlogerie (MIH) and Zenith. In its early days, the reputation of Zenith was notably built on the reliability of its marine chronometers, which served to calculate the position of ships at sea. It was the legendary 18th-century age of maritime exploration when marine chronometers were first invented, imbued with the thrill of adventure and the call of the open sea, that Zenith wished to evoke in creating the Captain line first launched in 1952.

Look: The Captain Winsor Annual Calendar is available in two versions: with a silver-toned or midnight blue dial framed by a steel case; or a silver-toned dial and an 18-carat pink gold case, each paired with a black or brown alligator strap with protective rubber lining.

Movement: The heartbeat of the watch is Zenith’s El Primero automatic chronograph movement, produced in-house for more than 40 years. The El Primero is the only series-produced movement to beat at 36,000 vibrations per hour, meaning the chronograph can time events to the nearest 1/10 of a second. Zenith reserves this automatic caliber for its own timepieces. The 42mm Captain Winsor model is equipped with the automatic El Primero caliber 4054 version with central chronograph seconds, continuous seconds at 9 o’clock and a 60 minute totalizer at 6 o’clock. The movement is decorated with côtes de genève and circular-graining, and visible through the sapphire crystal case-back.

Annual Calendar Complication: It was the museum’s curator, Ludwig Oechslin, who devised the ingenious construction: an annual calendar displaying the day of the week, date and month and that requires only one adjustment per year – a more accessible complication than the perpetual calendar for many chronograph enthusiasts. To ensure excellent readability, this 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.

Price: The steel version is priced at SGD12,700,  the rose gold version at SGD27,600 and both will be available in Singapore from next week onwards. It will be available at Cortina Watch, The Hour Glass, Sincere Fine Watches and other select retailers.
