Zenith Launches Two New Limited Edition Zero G Watches, Defying Gravity

Celebrating its 160th anniversary, the Le Locle Manufacture has reached new heights with its Defy collection. Both new models feature a stunning modern sapphire crystal structure.

Zenith has always been at the forefront of innovation. Since its founding in 1865, the brand has won over 2,300 chronometer awards, developed over 600 movements, and filed over 300 patents. One of its most significant milestones came in 1969 with the launch of the now-iconic El Primero caliber, the world’s first integrated high-frequency automatic chronograph movement. Since then, Zenith has continuously refined the El Primero caliber, increasing its accuracy from 1/10th of a second to 1/100th of a second. The brand has also continuously introduced other innovative products to enrich its product line.

Another significant achievement was the Zero G watch, patented in 2008. This was the first and only watch movement equipped with a gimbaled “gravity control” escapement module, a mechanism that counteracts the effects of gravity—one of the greatest challenges in mechanical watchmaking and precision timekeeping. Today, Zenith continues to innovate on this technology with the release of two new versions of the Zero G Perfect replica watch reviews.

The Effect of Gravity on Watch Movements

Watchmakers have long struggled to overcome the force of gravity. Depending on the position of the watch, gravity affects the regulating organ differently, altering its rate. As early as 1801, Abraham-Louis Breguet attempted to address this problem with the invention of the tourbillon. To recap, a tourbillon is a mechanical device with a rotating cage housing a balance wheel, hairspring, and escapement. This rotation helps to compensate for the inaccuracies caused by gravity. This solution worked well for pocket watches, which are usually stationary. However, for watches in constant motion, the situation becomes more complex.

To address this challenge in the watchmaking world, Zenith turned to a seemingly unlikely field: marine chronometers. These instruments must maintain stable time on ships subject to constant rolling and pitching. To achieve this, the marine chronometer is housed in a case suspended on a gimbal system, keeping it perfectly level and effectively counteracting the effects of gravity. With the Zero G watch, Zenith miniaturized this concept, integrating it into the sleek design of a watch.

The Next Evolution of Zero Gravity

Ten years after the launch of the Zenith Zero G, it was improved with a more compact “Gravity Control” gyroscope module, just 30% of the volume of the original model. Three years later, in 2021, the brand redesigned the entire movement again, employing a new architecture that makes the displays more open and revealing, placing them at the center of the sapphire crystal case. Now, two limited-edition sapphire crystal watches continue the brand’s 160th anniversary celebrations. best replica watches

In keeping with the anniversary theme, blue accents appear throughout both watches. One model features a blue sapphire case, showcasing the color scheme to its fullest, while the other retains a transparent sapphire case. Both models feature lapis lazuli dials displaying off-centered hours, minutes, and small seconds. The skeletonized, hand-wound El Primero 8812S movement, visible from both sides and featuring a zero-gravity module at 6 o’clock, fully demonstrates the brand’s expertise.
