The ultra-modern Zenith Defy Zero G (G for gravity) has a new skeletonized high-frequency movement coupled with the brand's patented gyroscopic Gravity Control module. The 44mm 18K rose gold watch houses a manual-winding 324-part movement, the El Primero 8812S caliber, which measures tenths of a second, beats at the high rate of 5Hz and offers 50 hours of power reserve. The newly reconfigured Gravity Control module (first unveiled at the Zenith Academy Christophe Colomb in 2011 in its original format) combines the regulating organ and balance wheel, and holds them in a horizontal position. Visible at 6 o'clock, the system acts similarly to a tourbillon escapement and cancels the e!ects negative of gravity on timekeeping. For the Defy Zero G, this 139-part module has been slimmed down and optimized for peak balance amplitude and precision. It is held in place by a gimbal suspension system inspired by ships' gimbals that were designed to correct variations in time resulting from the pitch and toss of a ship at sea. Time is indicated on the blued ring at 12 o'clock.
