While the Zenith Pilot Type 20 requires no introduction, the Pilot Type 20 Annual Calendar Tribute to Russell Westbrook —designed in collaboration with the young basketball player— deserves a closer look. As its name implies, it is equipped with an annual calendar —an elegantly discreet complication that might almost go unnoticed if it were not mentioned on the dial. The annual calendar differs from the perpetual calendar in that it does not take into account the additional day that is added to the month of February in leap years —every four years.

This is a complication that calculates odd and even months and also factors in the 31st day of August. In a nutshell, it is a useful function that avoids the wearer having to adjust his watch every month. Visually speaking, the day of the week and the month are displayed on the blue dial at 3 o’clock in a rectangular aperture. Just above it are the name of Zenith’s new ambassador, Russell Westbrook, together with his silhouette in action on the court and his signature.
