Introduced in 2021, the Zenith Defy Extreme is a beefed-up version of the Defy 21. The case measures 45mm across at a height of 15.4mm, and it is water resistant up to 200 meters. Inside ticks a self-winding El Primero 9004 movement, which can be admired through the see-through back as well as through front via the sapphire dial.
