Zenith Launches Defy Extreme Lapis Lazuli II and Ultraviolet Chronographs

Zenith has expanded its Defy Extreme collection with two new timepieces: the limited-edition Defy Extreme Lapis Lazuli II and the permanent collection Defy Extreme Ultraviolet. Both models continue the brand's approach to housing high-frequency mechanics within aggressive, architectural case designs. These releases serve as a contemporary extension of the Defy line, which traces its lineage to 1969 and the development of the high-frequency El Primero movement.

Technical Foundation

At the core of both models is the El Primero 9004 automatic calibre. This movement utilizes a dual-escapement construction, which distinguishes it from standard chronograph movements that rely on a single balance wheel to perform multiple tasks. The timekeeping mechanism operates at a traditional frequency of 5Hz (36,000 vibrations per hour), while a separate, independent escapement dedicated to the chronograph runs at 50Hz (360,000 vibrations per hour). This architecture allows the central chronograph hand to complete a full rotation every single second, enabling the measurement of elapsed time to 1/100th of a second. The movement provides a 50-hour power reserve for timekeeping and approximately 50 minutes of autonomy for the chronograph function.

Defy Extreme Lapis Lazuli II

The Defy Extreme Lapis Lazuli II is limited to 50 pieces. It features a 45mm case measuring 15.4mm thick and 51mm lug-to-lug, constructed from a blend of forged carbon and titanium. The use of forged carbon results in irregular, matte surfaces that contrast with the deep blue lapis lazuli stone counters on the dial. Because the stone is natural, each piece displays unique pyrite inclusions. The watch includes yellow gold-plated applied markers and faceted hands filled with Super-LumiNova. It is sold with a black rubber strap and an additional black Velcro strap. While some outlets report a price of CHF 32,900 or EUR 36,800, others list the price at $37,100.

Defy Extreme Ultraviolet

The Defy Extreme Ultraviolet is part of the standard collection and features a microblasted titanium case. The watch revives an aesthetic concept first seen in the 2020 Defy 21 Ultraviolet, now adapted for the more robust Defy Extreme chassis. The dial consists of violet-tinted sapphire elements and purple counters, providing a semi-transparent view of the movement. The star-shaped rotor visible through the caseback is finished in a matching violet tone. The model is compatible with three strap options: a violet rubber strap, a microblasted titanium bracelet, and a black Velcro strap. Pricing for the Ultraviolet is reported at CHF 17,900, EUR 20,200, or $20,100.

Strategic Context

Zenith’s recent releases reflect a broader trend of utilizing the Defy Extreme platform for material experimentation and color-focused designs. The brand has previously introduced several variants in this series, including the Pantone and Chroma models, as well as the Mirror, Glacier, Desert, and Jungle editions. The inclusion of lapis lazuli is noted as being in conversation with other Zenith models released throughout the year, such as the Chronomaster Original Triple Calendar.

Industry commentary suggests these watches are designed to appeal to younger collectors by combining horological technicality with high-impact visual aesthetics. As Zenith continues to leverage its high-frequency heritage, the company maintains that both models are currently available through its official boutiques and select authorized retailers.
