There is a lot more to the Winsor from Zenith's 'Captain' range of watches, than initially meets the eye. On the dial of the watch are displayed the day, date and month as is normal for an annual calendar. But this clever, simplified system requires only one adjustment a year during the transition from February to March and manages to cut down the number of components needed to track the days from 40 to just 9 moving parts. The advantage for the user is simplicity of use and precision, a philosophy echoed in the pared-down design of the watch. It also means that there is more room for the chronograph, which in this case is the legendary El Primero, the most precise automatic mechanism of its kind. The Winsor, developed in conjunction with the Musée International d'Horlogerie, is a clever union of two very useful functions, all neatly accommodated in a handsome rose-gold case.
