Zenith El Primero Chronomaster Open Heart 22.2150.4062/91.C752 38mm (2019)

Zenith, founded in 1865, is one of the most prestigious Swiss watch manufacturers, renowned for its innovation in high-frequency chronographs. The El Primero movement, introduced in 1969, was the world’s first automatic chronograph with a high-beat 36,000 vibrations per hour (vph), allowing for unparalleled precision. The Chronomaster collection, which emerged as an evolution of the El Primero line, blends heritage craftsmanship with modern aesthetics. The Open Heart design, introduced in the early 2000s, showcases the movement’s escapement, allowing wearers to admire the legendary El Primero mechanism in action.

The Zenith El Primero Chronomaster Open Heart is a masterpiece of high-precision watchmaking, showcasing Zenith’s legendary El Primero movement and an elegant rose gold case with a diamond-set bezel. This watch blends technical excellence with sophisticated luxury. The open-heart dial showcases the legendary El Primero movement, known for its high-frequency precision, while the rose gold case and diamond bezel add elegance. The slate grey dial provides a modern contrast, making this timepiece both a collector’s piece and an everyday luxury companion.

The Zenith El Primero Chronomaster Open Heart Slate Grey (Ref. 22.2150.4062/91.C752) continues this tradition by combining the iconic high-beat chronograph movement with luxurious rose gold and a diamond-set bezel, making it both a technical and aesthetic masterpiece.
