The Zenith El Primero Chronomaster Open (Ref: 03.2040.4061/69.C802) is a bold fusion of heritage and innovation. Housed in a 42mm stainless steel case, it features a silver dial with the iconic tri-color sub-dials and a daring aperture that reveals the high-frequency El Primero 4061 automatic movement, beating at 36,000 vibrations per hour. This timepiece not only offers chronograph functionality but also showcases a silicon escape-wheel and lever, visible through both the open dial and sapphire case back. Paired with a blue fabric strap, it exudes a sporty yet sophisticated charm.
