COVER-Zenith Defy Zero G Watch

Any horology enthusiast will tell you that the tourbillon is one of the most exquisite and expensive complications that can be found on a timepiece. But, it seems like Zenith may have finally come up with an alternative and possibly improved approach. Let’s take a closer look at one of the most talked about watches from Baselworld 2018, aiming to innovate this industry, the “Zenith Defy Zero G”.  


Just last year Zenith rolled out their experimental “Defy Lab” (Ref#: 27.9000.342/78.R582) model with a totally new envisioned regulator, which consists on replacing the sprung balance with an oscillator that forms a monolithic whole, thus avoiding friction wear and eliminating the need for any lubrication. The components are also made of monocrystalline silicon which are not susceptible to: temperature gradients, gravity or magnetic fields! Zenith claims all these factors insures the watch maintains the same degree of precision for 95% of its power reserve; as you can read more about here.

Now, these new “Zenith Defy Zero G” come in a 44mm case available in either: brushed titanium or an 18k rose gold edition; both with a transparent exhibition case back, which allows to view the inner workings of the mechanical movement.

Time is exhibited on an open-worked dial that sees thru to the case back. To actually read time there is an off-center dial ring positioned on the upper-half of the overall dial area, with small minute index markers and larger marketing for every 5-minute increment, which doubles as hour index markers.


Piercing into the side of this ring dial is a sub-seconds dial that also contains small marking to assist with reading the time. There is a power reserve indicator on the right side of the case, aligned between where we would typically find the 2 and 3 o’clock positions. The central hands have been fitted with a luminescent filling for an enhanced legibility. And last but not least is the aforementioned rotating tourbillon in all its glory “floating” around at the 6 o’clock position.

This “Zenith Defy Zero G” (References below) is powered by a hand-wound mechanical movement, caliber El Primero 8812 S with 41 jewels, 324 components and 36,000 Vph. Power reserve on this timepiece can last up to 50 hours, when fully wound. As aforementioned this movement features a “Gravity Control” gyroscopic module that ensures horizontal positioning of the regulating organ at all times. For this updates 2018 version, the model has been constructed 30% smaller than on earlier versions.


Mounted to the watch is either an 18k rose gold or a titanium brushed bracelet, both secured to the wrist by a double folding clasp; or, a black rubber with alligator leather strap, also secured to the wrist by a double folding clasp. All buckles are made to match each versions case material of either 18k rose gold or titanium. For more up to date information visit the official Zenith website here.
