Zenith DEFY Zero G Sapphire Watch
Gravity is the bane of watch-making accuracy. Following years of development, Zenith has overcome it (mostly) with the Gravity Control escapement module of the El Primero 8812 manually wound movement. It uses a gimbal-mounted mechanism to maintain a perfectly horizontal position at all times for outstanding accuracy. To highlight this innovation, the openworked dial features it at 6 o'clock, while the 46mm cases are crafted in full sapphire — either clear or blue — so as not to block the views. Limited to 10 examples of each color.
