The El Primero 18.2110.400/01.C498, seen from the bench
The Zenith El Primero 18.2110.400/01.C498 in 18-karat rose gold represents the evolution of the legendary 1969 automatic chronograph calibrated at 36,000 alternations per hour. The El Primero 400B movement operates at 10 Hz with column wheel technology and natural escapement, delivering precise chronographic function without backstop. The 42 mm rose gold case with 18 mm lug width balances athletic proportions with refined wrist presence, while the dial showcases warm luminosity enhanced by subdials for running seconds, date, and chronograph function.
