The Zenith Defy Extreme Chroma Series comprises two limited-edition timepieces launched in December 2025. This series continues the innovative color style of the 2022 and 2023 Chroma series, while incorporating the high-performance DNA of the Defy Extreme series. Here are some key details:
Design: Titanium and Ceramic Combination + Gradient Rainbow Aesthetics
Case and Materials: Both watches feature a 45mm diameter case, 15.4mm thickness, and 51mm lug spacing, balancing presence and comfort. One model uses micro-blasted titanium with a black ceramic bezel, crown, and pusher protection; the other combines brushed and polished titanium with white ceramic components. This interplay of different processes and materials enhances the watch's architectural silhouette, aligning with the futuristic style signature of the Defy Extreme series.
Dial and Details: Equipped with a skeletonized sapphire crystal dial, offering a clear view of the internal movement. The dial markers feature a three-dimensional design with rhodium plating and are covered with an iridescent lacquer, creating a seamless gradient effect between the markers and printed lettering and the movement's color scheme. A 30-minute counter, small seconds counter, and chronograph counter are located at 3, 6, and 9 o'clock respectively, while a chronograph power reserve indicator is at 12 o'clock. The tips of the sub-dial hands also continue the gradient color scheme, making the complex dial both clear and visually striking.
Movement Configuration: High-Frequency Precision + Unique Visual Design This series is powered by a custom-designed El Primero 9004 automatic movement, the core of its performance. The movement employs two independent escapement systems: one operates at 5 Hz (36,000 vibrations per hour) for daily timekeeping, while the other drives the chronograph function at an ultra-high frequency of 50 Hz (360,000 vibrations per hour), achieving a 1/100th of a second accuracy. The central chronograph seconds hand completes one revolution of the dial per second, ensuring precise and intuitive chronograph readings. The movement bridges undergo a multi-color PVD coating treatment, creating a unique "mechanical rainbow" visual effect. The star-shaped rotor on the case back also features exclusive color schemes: a bright blue rotor on the black version and an electric green rotor on the white version, further echoing the overall color theme. Furthermore, the movement is TIMELAB chronometer certified and offers a 50-hour power reserve when fully wound.
Practical Features: Versatile and Easy to Use
Water Resistance and Protection: The watch is water-resistant to 20 ATM (equivalent to 200 meters deep) and features a screw-down crown, making it suitable for various demanding scenarios such as diving, meeting the needs of daily and outdoor use.
Interchangeable Straps: Each watch comes with three quick-release straps: a rubber strap matching the case color, a titanium bracelet, and a black Velcro strap. These can be easily switched without tools using the quick-release system on the case back, adapting to different occasions such as casual and sporty settings.
The two watches have reference numbers 97.9113.9004/33.I200 (black) and 95.9114.9004/69.I203 (white), making them both collectible and unique.
