Base ETA E56.411

Quart movement with precision of ±5 s/yr, Gear Position Detection (GPD) system that resets the hands after an impact or magnetic field exposure, smart crown, very long battery life and perpetual calendar that extends to 2399. It is equipped with a second time zone and a light-driven management system, known as Flash Setting. This movement can be easily set manually using the crown, or through its innovative Flash Setting function. Flash Setting is what makes fast and direct time setting possible without using the crown, while providing rigorous precision in displayed time. The system relies on the user’s smartphone and dedicated application but requires no external connection, such as WiFi or Bluetooth. The information recorded in the application is transmitted via light sequences emitted by the smartphone’s flash to a tiny opening on the watch dial, concealed in the number 12. The Swap function offers another remarkable benefit, allowing the user to interchange home time and travel time on the display simply by applying pressure to the crown, for even greater reading comfort anywhere in the world.
