Zenith Defy 21 Ultrablue

Zenith expands its Defy 21 series by presenting a new model in cool tones of deep indigo and electric blue.

This timepieces with a Micro-blasted titanium case houses Zenith’s state-of-the-art 1/100th of a second chronograph self-winding movement. The El Primero 9004 automatic calibre beating inside this watch has two escapements: one for the watch and second one for the Chronograph. These escapements have the beating frequency of 5 Hz and 50 Hz respectively.

The partially open dial of the Zenith Defy 21 Ultrablue features slightly overlapping closed chronograph counters, finished in a grey tone matching the deep grey of the case with contrasting white markings for legibility.

The vividly blue movement is accentuated by the DEFY 21’s uniquely avant-garde movement conception and design with open and angular bridges. A white-tipped central 1/100th of a second chronograph hand makes a complete revolution above the dial in one second.

Allowing the blue bridges of the movement to truly stand out while providing a more striking contrast, the faceted 44mm titanium case of the DEFY is given an entirely matte sandblasted finish, bringing out its darker metallic nuances and absorbing much of the light that hits its surface.

Complementing the tones of the open movement, the black rubber strap features a blue cordura-effect rubber insert with tone-matching stitching.

The DEFY 21 Ultrablue is available for purchase at Zenith Boutiques around the world as well as its regional online boutiques from March 2021.
