Featuring an annual calendar complication, a chronograph, and a fume dial – the El Primero Winsor Annual Calendar Boutique Edition makes Zenith’s often forgot about annual calendar chronograph worth remembering.

Specifically, the new brown-gold fume dial – contrasted by rhodium-plated applied Arabic hour numerals and rhodium-plated hour, minute, and second hands – transforms the watch into quite the stunner.

Apart from the dial, this El Primero Annual Calendar is the same as previous models, with a 42 mm x 13.85 mm polished stainless steel case, an exhibition caseback, and powered by automatic caliber 4054. Running at 5Hz, the 30 mm x 8.3 mm El Primero movement consists of 29 jewels and 341 total components and has a 50-hour power reserve.

The annual calendar function also called a “complete calendar” keeps the date set with only one adjustment needed per year at the end of February (not to be confused with a “perpetual calendar” which takes it a step further and requires no adjustment in February). For the Winsor Annual Calendar, the day and month are displayed in a double-framed rectangular aperture at 3 o’clock; and the date is indicated in the aperture located at 6 o’clock.

The chronograph features a 60-minute counter at 6 o’clock and a centrally mounted chronograph seconds display. The baton-shaped chronograph hands are blued, to help better differentiate from the timekeeping hands. Start and stop are controlled by the flat pusher at 2 o’clock and reset by the pusher at 4 o’clock.

Each piece comes with a brown alligator leather strap with a protective rubber lining and a triple folding steel clasp. Water-resistance is 50 meters. The retail price is $9,500. (Ref. 03.2072.4054/18.C711)
