In the world of haute horlogerie, few names resonate with innovation and craftsmanship quite like Zenith. As the brand celebrates its 160th anniversary, it continues to push the boundaries of mechanical watchmaking with two stunning additions to the DEFY collection: the Zenith DEFY Zero G Sapphire in Blue and the Zenith DEFY Zero G Sapphire Transparent. These new limited edition watches, each produced in just 10 pieces worldwide, are more than timepieces—they are the ultimate expression of engineering, design, and technical prowess.

Crafted entirely from sapphire crystal, one of the hardest and most visually striking materials in watchmaking, both models offer a fully transparent view into the groundbreaking Gravity Control mechanism—Zenith’s patented, gyroscopic escapement system that neutralizes the effects of gravity in real time. Paired with a skeletonized El Primero 8812S movement, a lapis lazuli dial evoking the starry sky, and exquisite finishing throughout, each Zenith piece is a cosmic fusion of science and art. The Zenith DEFY Zero G Sapphire isn't just a celebration of the brand’s history—it's a glimpse into the future of horology.

At the heart of the DEFY Zero G is a patented marvel: the Gravity Control module, a gimbal-mounted escapement that neutralizes the effect of gravity in real time. While traditional tourbillons attempt to average gravitational errors over time, Zenith's Zero G movement eliminates them completely by maintaining the escapement in a perfectly horizontal position regardless of wrist movement.

This mechanism was inspired by the marine chronometers of the 18th and 19th centuries, which used gimbal-mounted cases to remain level aboard ships. Zenith has miniaturized this concept into a wristwatch for the first and only time, creating a feat of micromechanical mastery unmatched in the industry.

The manual-winding El Primero 8812S movement is an openworked marvel, beating at 36,000 VpH (5Hz) and offering a 50-hour power reserve. Positioned at 6 o’clock, the rotating Gravity Control module is both the visual and mechanical centerpiece of the watch. It includes:

• Silicon escapement wheel and nickel-silicon anchor for anti-magnetic performance.

• A double-arrow regulator, inspired by Charles Fleck's chronometer design.

• Laser-engraved platinum counterweight, shaped to resemble a celestial body.

• Dual-tone finish (blue and rhodium) with starry sky motifs on bridges and plates.

This movement is not only a display of Zenith’s technical ingenuity, but also a tribute to traditional watchmaking reimagined for the modern era. Containing over 139 components within the Gravity Control module alone, the mechanism showcases masterful miniaturization and mechanical precision. The unique conical gear transmission ensures that torque is delivered consistently to the escapement, regardless of the module’s orientation, maintaining peak chronometric performance. Every visible element is meticulously hand-finished, reinforcing the movement’s luxury appeal. It’s a true feat of engineering—both a conversation piece and a collector’s dream.

Complementing the technical sophistication is a lapis lazuli dial—a deep blue stone flecked with golden pyrite that evokes the starry night sky. Every dial is naturally unique due to the organic texture of the stone, and features:

• Offset hours and minutes at 12 o'clock.

• Small seconds at 9 o'clock.

• Power reserve indicator at 3 o'clock.

• Rhodium-plated hands and hour markers, coated with SuperLuminova SLN C1 for low-light visibility.

Zenith has long been a name synonymous with precision, innovation, and heritage. From winning over 2,333 chronometry awards to pioneering the world’s first automatic chronograph with the El Primero, Zenith’s legacy continues with the DEFY Zero G Sapphire.

This is not merely a timepiece; it is a symbol of the future of Swiss watchmaking—where science meets art, and gravity holds no sway. Every component, from the gimbal-mounted escapement to the sapphire case and lapis lazuli dial, reflects a brand that dares to dream bigger, craft finer, and deliver the extraordinary to those who expect nothing less.

With the DEFY Zero G Sapphire, Zenith reasserts itself as the heart of watchmaking. A celebration of 160 years of excellence, this release encapsulates everything that makes Zenith a standout in luxury horology: relentless innovation, breathtaking design, and a refusal to settle for the ordinary. For collectors and enthusiasts alike, this is more than a watch. It’s a once-in-a-generation masterpiece.
