HIGH ENERGY

When Zenith launched the Defy 21 Ultraviolet with vibrant purple movement bridges last year, the idea to use such a high-frequency colour was to highlight the speed of its 1/100 of a second El Primero 9004 chronograph movement. It continues the concept with the Defy 21 Ultrablue's bright blue movement bridges that contrast with its 44mm sandblasted titanium case.
