In this watch Zenith have matched the unparalled accuracy of the legendary El Primero movement with an annual calendar module designed by Ludwig Oechslin the creator of The Freak watch for Ulysse Nardin. The module uses 3 concentric discs to display day, month and date and has only 9 moving parts compared to the 30 or 40 parts of most annual calendar movements. This example was sold new in 2019 and has its box and papers. It is in excellent unpolished condition with some minor hair-line scratches on the case.
