The Espada combines understated elegance in a 40mm case with Zenith’s high-frequency El Primero movement, which beats at 36,000 vibrations per hour (5 Hz) and offers a power reserve of 50 hours. The Calibre 4650B version of the movement used in this model provides hour, minute and central seconds display, which is conveyed by elegant facetted hands and applied, facetted hour markers against a graduated dial.
